Shopping For a New Computer – Understanding Total Cost of Ownership

As owner of a computer repair service center it is quite common to see customers who are contemplating simply buying a new computer as opposed to repairing their existing computer. Many of these customers tend to believe that a $300-400 computer that they’ve seen in an advertisement from one of the big box stores may be the answer to their problem and eliminate their need for service. While it is true that there are some models of new computers that are sold in the $300-400 range the initial purchase price is only one factor to consider when buying a computer. More important than the purchase price is what’s know as the Total Cost of Ownership, or TCO. Determining the TCO of a computer involves adding together the purchase price as well as all of the incremental costs associated with owning it to determine the true cost of the computer to its owner over the life of the machine. Determining the TCO of a computer involves adding together the following:

  1. The initial purchase price of the computer
  2. The cost of service, maintenance and repair work over the life of the computer
  3. The cost of lost productivity during any times that the computer was out of service
  4. How many years the computer can be expected to last for

As you might expect, it is common for computers with very low initial purchase prices to have among the highest Total Cost of Ownership. Accounting people at big firms have understood this for many years which is why you will never see a Fortune 500 company using any of the models of discount computers that you will see on the shelf at Best Buy, Circuit City or any of the other big box stores. Almost every manufacturer (Dell, HP, etc.) offers two separate lines of computers. One line is referred to as their “Business” class computers and the other is the “Home” line of computers. The primary difference between the two is that the business line of computers are built for people who understand TCO. The initial cost of a business computer will always be higher than the “home” line even though the CPU speed, memory and hard drive size may be the same, but you will be getting a computer that is built with better parts: not necessarily faster, but less likely to break down and more economical to service if it does break.

The home lines of computers are built based on an entirely different measurement– mainly that having a broken computer isn’t going to cost you anything. This unfortunately for an uninformed consumer is often not the case; especially once the computer is out of warranty which on new computers is generally only one year. For the do-it-yourself type of computer user who has a good backup system, doesn’t rely on the computer for important business functions and is able to perform their own repairs, the home model computers sold at the big box stores are often a worthwhile option. For everyone else you may benefit from buying a business class machine. You can find purchasing prices and options for business class computers on the websites of any of the major manufacturers, or by contacting your local computer repair service center. Many computer service centers will also have off-lease or refurbished business model computers to choose from as well.

Mobile Phones Cause Cancer?

Cell phones’ electromagnetic radiation is said to cause brain cancer. Is it true? People are concerned about the fact that high levels of microwave radiation pose harmful hidden dangers and realize they demand protection that will ensure their safety and help them keep in a healthy and good condition. Although there are many shields available on the market the don’t protect them against radiation from towers, antenna or masts. So what can we do to prevent ourselves from emission that kills our brain cells?

Mobile phones radiation

Mobile phones are used worldwide these days, the invention of pocket sized mobile phones startled the implementation of mobile phones into our daily lives. As far as I’m concerned, there are people who have a kind of emotional attitude to their mobiles, they would rather die than not use mobile at all. To make things worse, there are scant numbers of people who can imagine life without mobile phones and being in touch with their family or friends 24/7. Since mobile phones depend greatly on radiation there is a concern if they have any harmful effect on people’s health. The industry tries to con the public and make them believe in lack of any negative effect of mobile phone industry as it brings billions of dollars every year.

So far, numerous studies and tests have been conducted to check whether mobiles are harmful or not. The controversy and debates over the effects of usage mobile phones and their possibility to cause brain tumors are of special interest of scientists, communication workers and ordinary people. The reason for such an interest is that cell phones belong to the group of products that emit electromagnetic radiation e.g microwave oven, electric clocks, computers or other appliances. This is non ionizing radiation which is claimed not to cause any damages to the cells. Ionizing radiation e.g. x-rays damages DNA of the cells, results in mutations and birth defects.

According to some researchers using a mobile phone has no direct effect on getting malignant brain tumors. The harmful effect of mobile phone is achieved through their thermal effect. This type of radiation causes dielectric heating which heats up living tissue – your one part of the head will be warm. This could be called microwave radiation – according to The Journal of Cellular Biochemistry this radiation interferes with DNA and destroys its repair mechanisms. Apart from that microwave radiation make cells age rapidly or cancerous cells grow quicker, as Italian scientists demonstrated.

Brain damages

Even tiny, minimal doses of radio frequency accumulate and lead to harmful effects and damage the brain cells. Although it is the antenna which is said to emit the biggest amount of radiation the mouthpiece and keypad also leak radiation, penetrates the brain, ear and eye tissues. According to other researchers mobile phones’ side effects include:

– nerves in the scalp are damaged

– blood cells leak hemoglobin

– headaches, fatigue

– loss of memory,

– the strange ringing in the ear, sense of smell is impaired

– retina may be damaged, eyes can get cancer

– the amount of white blood cells is reduced

– digestive problems may appear, bad levels of cholesterol are risen

– the barrier to viruses and toxins is open

– asthma is triggered

– the endocrine system stops working properly

– skin rash and burning sensation of skin is evoked

University of Utah researchers claim that this radiation is especially harmful for children: it may cause mood changes, learning problems. Also human embryos can be damaged so pregnant women are advised to keep away from mobile phones. What might be shocking for some people, using mobile phones is even more harmful within the car or any metallic cage. That is due to the fact that the cell phone has to increase its field and intensify the radiation, extremely high electromagnetic field is generated then. The drivers reaction time is longer and less effective due to the damages of the brain. One hour long exposure to mobile phone radiation makes brain cells shrink.

Nevertheless, cell phone companies spend million of dollars on advertising and nothing is said about dangers and threats. The huge amounts of radiation cannot be ignored, especially that their emission is so vast and we are surrounded by huge levels of radiation every day. There’s literally nothing that protects us from RF energy. No one dares to fight against cell phone companies, that would be risky, they are simply the same as tobacco companies several years ago.

What should we do?

1. Use the external antenna in the car.

Most mobile phones have an attachment to the external antenna, all energy can be kept outside the vehicle.

2. Use hands-free device

Each place to keep your mobile is better than sticking it to the ear.

3. Use voice recognition

Instead of touching the mobile you can say what number you want to dial.

4. Use digital phones

Analog phones use about 1.3 Watts which twice as much as in digital phones (0.6W)

5. Make your conversations shorter

Cut it as short as possible

The correlation of mobile phone using and brain cancer has yet to be discovered because the brain tumors and cancers take years to develop. That makes them almost impossible to study the long-term effects of microwave radiation exposure. As non-ionizing radiation has got heating effects it surely has the greatest effect on the eyes and testes, there’s lower amount of blood vessel that cool these areas. The thing which people should keep their distance from is the antenna. Hand-held mobile phones are dangerous because they deliver the radiation energy to the small fragment of person’s body.

Who is at risk?

People who are most likely to suffer from the effects of mobile phones overuse. These include: telecommunication workers who install, test, maintain the equipment, laboratory workers, military radar workers, electrical workers, amateur radio operators.

Although some scientist claim that cell phone radiation hasn’t got detrimental effect on health they are also unsure that they are completely safe. One must remember that cell phones are quite new, even though they haven’t caused cancers so far the time may prove they actually do.

There are still problems with finding any credible source that claims that cell phones are dangerous. Since news media are not reliable resources of knowledge as they are searching for scandals to attract public attention. Therefore, we still have to wait a while to receive any credible results.

Computer Repair Technicians Taking the Easy Way Out – The Wipe and Reinstall Fix

This “syndrome” in the computer repair industry ranks near the top of my frustration list of practices by some computer repair technicians. I am referring to the practice of a few unprofessional computer repair technicians, and even some big company franchises, taking the easy way out to fix a computer by telling the customer that they have to wipe the hard drive and reinstall everything.

In my head, I am still trying to figure out how someone can call wiping and reinstalling a “fix” for any computer repair problem. On my list of remedies, that is my last resort. Generally it kind of leaves me feeling a bit defeated. But, since I rarely have to ever do that, I think only 3 or 4 times in the last 18 years, it is not a big issue for me.

So why do so many computer repair technicians find it so easy to resort to destroying the customer’s data and wiping their hard drive as a solution to a computer repair problem? Here are a few of the reasons.

  1. They really do not know how to fix the problem. This is the number one reason. Most of the time this is the approach most often used by technicians that have little experience in actually troubleshooting and fixing computers, You know who they are. Its the guy, often barely out of high school, that grew up playing with computers and built his own gaming system so he thinks he is an expert at repairing computers, or the person that home studied the certification books and proceeded to get a certificate because he answered all the question right on a piece of paper. Any way it goes, they just don’t have the experience and this is their only solution. What is worse is they are taking advantage of the customer that is trusting their “expert” conclusion that this is the ONLY solution to their problem, often leaving the customer with a feeling of regret for not having backed up all their data, documents and pictures and losing them because of the reinstall
  2. Time and money equals profits. It takes longer to troubleshoot and attempt remedial actions on a computer with complicated problems. Often a consumer is looking for the best price for the computer repair. In order to remain competitive and maintain a volume of business, a computer repair company may resort to the wipe and re-install of a computer because it takes significantly less time than actually resolving the issue. Thus, they can make more money by taking the fastest route to getting the computer up and running again. Again, not usually in the customer’s best interest because they end up generally losing their data and having to reinstall all of their software applications on their own.
  3. Laziness. This comprises a little of both of the above plus a poor attitude, but is really self-explanatory. The computer tech or the company philosophy is to take the easy way out, avoid possible complications, get the computer out the door repaired, and do so with the least effort, time and expense. It is a “repair mill” mentality. In general, they just don’t care about the customer. Rather, it is all about whatever is easiest and most profitable. Again, the customer becomes an innocent victim of unprofessional business attitudes and practices.

A comment response by a self-proclaimed computer repair guru on a forum posting by another newbie technician asking “What’s a good turnaround time on computer repair for consumers?” read the following: “It really depends on clientele, If you want to do this in a full time extent, you should be able to do this in about 8 – 12 hours. If you just reimage the computer it shouldn’t take more than 2 hours.” I guess we know how he operates.

A true technician can resolve nearly any problem without resorting to wiping a hard drive and reinstalling the operating system, also referred to as reimaging a computer. A technician with a genuine concern for the customer’s best interest will use everything in their arsenal to fix a problem before resorting to a total reimaging of a computer system.

In my own computer repair company, I can site multiple instances wherein a customer brought a computer to me because they were told by another computer repair person that it was necessary to reimage the customer’s computer resulting in total loss of their data, only to find that indeed, it could be fixed without any loss. Yes, sometimes it costs more than reimaging a system due to the longer repair processes, but the customer more often than not would rather pay a bit more than lose all their data, and all too often, their precious libraries of family memories on the computer in digital pictures.

My advice to consumers is to ask around and check the reputation of the computer repair tech. Don’t be gullible and easily accept a computer repair technician’s assertion that a total wipe and reinstall of the hard drive is required. Drill them on the reasons why it is necessary, and what the alternatives are. At the very least, always tell a computer repair person or company that they should contact you for authorization before wiping your hard drive and reimaging your computer. Be aware as well, that many of the large franchise operations use a business model wherein a series of mandated minimal troubleshooting steps are undertaken before the company policy dictates a complete reinstall of the computer is required for problem resolution.

Mobile Phone Deals – Choosing the Right Deal for You

When discussing mobile phones, this is probably the number one question I am asked by friends, family and colleagues. Unfortunately this is not an easy question to answer without finding out more about how a person uses their mobile phone. How often do you actually use your handset to make calls? Do you go online with your phone? Would you be lost without GPS navigation on your phone? (Pardon the pun).

Choosing the right type of mobile phone deal can be a tricky business. There are so many options available to you that the process can become confusing. In this article I will give you an overview of the three main types of mobile phone deals and present some of their advantages and disadvantages in the hope that it will help you find a deal that’s right for you.

Contract deals:

Contract deals are the most popular type of mobile phone deals. A contract deal will tie you to a contract for a set length of time, and will include a phone (sometimes free), a sim card and a set allowance of monthly minutes, texts and data. You will be billed extra if you go over the set monthly allowance.

Advantages of a contract deal:

  • Get the latest and most technologically advanced phone for (usually) no initial cost.
  • Pay a fixed amount per month for a set allowance of minutes, text messages and data: you can choose the right allowance to suit your own usage patterns.
  • Many mobile phone shops and websites offer free gifts and cash back deals with a contract, although you should be careful with these types of deals. Always read the small print as they can end up costing you more over the long run.

Disadvantages of a contract deal:

  • As the handset is subsidised by the network provider you can end up paying much more over the course of your contract than if you purchased the phone outright.
  • You will be tied into a contract for at least 12 months and often 24 months, meaning little chance of upgrading before you contract expires.
  • The handset is often locked to one provider’s network, meaning you cannot use it with another provider’s network after your contact has ended, although sometimes these phones can be unlocked at a cost.
  • You may not be able to get a contract deal unless you have a good credit record.

Sim only deals:

Sim only deals have become very popular in the last few years. When you sign up for a sim only deal, you will be sent a solitary sim card: no mobile phone is included in the deal. You must use the sim card in your existing handset.

Advantages of sim only deals:

  • It’s cheap. Purchasing a sim only deal usually involves no initial outlay of cash and often gives you more minutes, texts and data then a contract deal for the same monthly cost.
  • The length of the contract can be very short. Sim only deals range from as little as 30 days all the way up to 24 months, meaning you can call time on the contract when you want to. (Again, pardon the pun).

Disadvantages of sim only deals:

  • A mobile phone is not supplied with a sim only deal. This means that you will have to own a compatible mobile phone which may have to be unlocked prior to purchasing a sim only deal.

Pay as you go (PAYG) deals:

Pay as you go deals have been around almost as long as contract deals. With a PAYG deal you can purchase a phone and a sim card and only pay for the minutes, texts or data that you actually use. Payment must be made in advance of using the phone.

Advantages of PAYG deals:

  • PAYG is a relatively cheap way to own a mobile phone.
  • You only pay for the minutes, text and data you actually use, so no monthly bills and no nasty surprises.
  • No credit is given: a clean credit record is therefore not required.

Disadvantages of PAYG deals:

  • Pay as you go phones do not tend to be the latest and greatest mobile phones, often lacking the latest technology and applications. To be fair this is becoming less of an issue these days with many basic phones having some advanced functionality.
  • If you are a heavy user of your mobile phone you will probably end up paying more on PAYG then if you were to purchase a large usage allowance with a sim only or contract deal.
  • No credit is given: payments for usage must be made in advance so running out of credit can cut your conversation mid call!

Conclusion:

So, what is the best deal for you? Generally speaking, if you hardly ever use your phone, then a PAYG deal is recommended. It will be the cheapest option for you in the long run. However, if you’re always on the phone and enjoy social media applications and the latest features, then a contract or sim only deal is recommend.
