Laptop computer reviews represent a very significant source of information for those who are interested in getting a new computer to help them in their occupation or to provide entertainment at home. But being an informed buyer is not an simple job for anybody.

Even though we may think that we are knowledgeable enough, we may later, discover that we were mistaken in the decision we took. Or perhaps that mistake was made during the phase before the decision itself was made? During the research period perhaps?

The rule of thumb is to try to read more than a few laptop computer reviews more before you consider you have obtained enough information to be able to do what you need. Why is that so necessary?

To start with, laptop computer reviews are written by people who are paid to write quite a lot of reviews perhaps even in one single day. As a result of this, whether the writer wants to or not, he/she may end up saying pretty much the same thing about almost every laptop computer or even just glossing over the details.

Or, she/he may end up leaving bits of information out. Making mistakes is fairly common in human work when fatigue and tedium enter the picture.

Another reason why you should read as many laptop computer reviews as possible is that this way you will definitely come across reviews made by some people who actually use the laptop computer you are interested in. These forms of reviews and assessments are the ones that will most likely provide you with a truthful picture of how this laptop computer really works.

People who have actually used the computer will also have several points of view that big magazine reviewers may exclude from their pieces or reviews. These kinds of laptop computer reviews will also give you an idea about whether you are thinking about buying a laptop computer that is ideal for you or whether you are thinking about buying something that is too advanced for your requirements and so unnecessarily expensive, or too basic, and therefore cheap but useless.

Last but not least, different laptop computer reviews, especially if they come from several sites and consumers, will differ in the sort of information they will give you about the laptop computer. What may be absent from one assessment may be mentioned in another.

The whole mystery will not be over until you actually own that computer. However, the larger the number of reviews you read, the more accurate the image you will get. Above all, remember that ignorance of the details could cost you dearly and more than that, might even land you with a low quality laptop computer.

As with everything else, buying a computer is straightforward if you know what you are doing. For those who do not know though, it can be a complete nightmare. People who have had a computer before have a good idea about what they require and what they would like, but for those who have never had a computer before, all the components that make up a computer can appear bewildering.

The obvious answer is to buy the best that you can manage, but this still might puzzle some people, because the best is not always the most expensive. In the computer world, ‘the best’ normally means the biggest and the fastest.

Just to make it more perplexing, ‘the biggest’ here does not always mean in size, but in capacity. The only large size that is important is the monitor. This is a quick rundown of how to buy a computer and its components:

Before you buy a computer, think about why you want one. If it is for educational purposes: that is surfing the web and looking up content, you do not have to have more than a basic desktop computer. If you are constantly on the move, then you might require a laptop, or maybe cyber cafes will meet your requirements.

This kind of machine is also ample for writing letters and emails and almost any type office work. Top flight computers are only required by games players and exhibitionists.

Purchase a complete computer. That means acquiring a kit of: CPU (the ‘computer’), monitor (screen), keyboard, mouse, speakers and printer. This way you will just have to plug everything in and off you go – you can be sure that they are all well-matched.

When you buy your next computer, you can buy all the components individually to get even better value for money or a system more precisely customized to your preferences.

Go for the largest screen, the fastest memory and fastest hard drive and the biggest memory (RAM) and biggest hard drive (gigabytes) that you can afford. You do not have to have a great deal of ’space’ for normal office work or normal surfing, but if you get into downloading music or films, then memory soon gets eaten up, although you could always add a new external (plug-in) hard drive later, in necessary.

Make sure that you buy a computer that is not too old, if you go second-hand. This is because you can up-grade computers for two or three years, but after that manufacturers change the casings and new components will no longer fit – planned obsolescence, it is known as.

Get your computer from a well-known, reliable local store and ensure that it has a good guarantee. Computers do not often go wrong, but you do not want to have to send it half-way across the country and wait three weeks for it to come back. If you are in business, get two. Perhaps a laptop and a desktop and synchronize the contents of both so that you always have your information.

Following these guidelines will ensure that the computer novice gets ‘enough’ of a deal and an acceptable machine that is fit for purpose without paying through the nose.

If you do not buy your home theater in one box, as many people do, then you will have to choose a screen at some point or another. However, not only that, but you may be faced with deciding between a TV-cum-monitor unit and a drop down canvas screen.

It really all depends on the dimensions of the room you want to use as your home theater. If you are going to convert the box bedroom into a movie theater, then a 28 inch TV screen might be enough for you, but if you are going to use a long room and people might be quite a few yards from the screen, then a projector and drop-down screen would almost certainly be the right answer.

However, for most people, a normal TV screen would be sufficient. There are several types of television sets on the market at the moment, so we will take a look at them in turn later. Firstly, I would like to talk about the dimensions. It has been standard practice for hundreds of years to hang a painting five times the diagonal of that painting from the viewer’s eyes. In other words, if a painting or a screen or a window, is two feet diagonally, then the best place to view it from is ten feet away.

This is a broad rule, it is not written in stone. Personal preference and eyesight come into it too. Therefore, if you used a 28 inch television set, the optimum viewing distance would be about 12 feet away. So, 28 inches would be ample for most spare bedrooms, but maybe not for a converted attic or basement. This relationship between screen and room size is the most important to get correct, otherwise the rest is a waste of money.

It all boils down to: do you like to sit in the front of the movie house or at the back? [We are only discussing viewing the film here]. If you like to be dominated by a huge screen, then the proportions I gave you must be decreased, otherwise they should be about accurate. Assess yourself: how far do you like to sit from your TV? Is it more or less than 5:1?

There are essentially three types of view screens and they are: plasma, rear projection and front projection screens. The first is the modern flat screen TV, the second the conventional TV and the third a system with a projector.

Plasma Televisions

These televisions give the best quality, especially for watching movies that are formatted for wide screen viewing. They have a much larger viewing zone than traditional televisions and they also come in a wide variety of sizes in order to adapt to many types of home theater needs. The biggest problem with these beauties is the price, but that is dropping every month too.

Rear Projection Televisions

This is the normal cathode ray tube TV that we have all been watching since were born. Their major problem is that they are lumpy, but that was not a problem for decades, so if it suits your room, do not let it be a problem to you now,

Front Projectors

This is what you see at the movies or on old Cine 8mm – the drop-down projection screen. But, do not write it off. It still produces high-quality images and for larger rooms, it is really the only screen for your home theater.

If you are thinking about setting up a home theater system, then there are three basic pieces of equipment to consider. They are the screen, the speakers and the player. Two of these components are directly related to the size of the room in which you will be sitting and where you will be seated.

All DVD players over a certain price are fairly good and you ought to listen to a couple to make up your mind. The same with speakers, although how many you will need is dependent on the dimensions of the room. The screen is more important and that is what I want to talk about here.

It will not really be of very much help to you to just go into a department store which stocks fifty or sixty television sets all in a line. You may find that you have a preference for one screen’s colour display over another, but the colours are controllable anyway by brightness, contrast and colour mix. You need to view the screen as it will be seen in your home theater.

In order to do this, I always advise getting a pen, paper, preferably graph paper, and a rule. Draw in the proportions of the room to the largest scale that the sheet of paper allows, maybe one inch for two feet or there abouts. Then draw a line to represent the screen against whichever wall you choose and finally add a few squares for the seating. Now measure the space between them and write that figure down, because it is very important.

Using our scale above, if the gap on paper between the screen and the seating is five inches, the distance in the room will be ten feet and ten feet is 120 inches. A good rule of thumb, when trying to work out screen size is the same one used for paintings, which is that the ideal viewing distance of a picture is between three and five times its diagonal measurement. Therefore, in our illustration, the ideal screen size should be between 40 and 24 inches. However, many experts put a minimum screen size for a home theater at 28 inches.

That may come as a bit of a surprise to many of you, because a lot of people think that the answer is the bigger the better. However, primed with this information, now go to the TV store and look at the TV’s again. You will find that if you get up too close to some sorts of screen the picture becomes rather poor, particularly with conventional television screens. Plasma and HDTV allow you to get a little closer without losing quality.

Another consideration is your age, or at least, the quality of your eyesight. Would you rather watch the film with your glasses on or off? Off for me, so I would tend towards the higher end of our scale or maybe even go above it. My eyes are not going to get any better, but I can always put my glasses on when the time comes that I cannot see my screen properly any longer. However, I want to put that time off for a while yet, so I would go for a 48 inch screen in this example for my home theater. Plasma, if I could afford it.

Is your computer’s case or casing of any importance to you? You might be asking yourself the question: why should it be? The fact is that the computer case is vital to the computer itself and also to some people.

Let’s begin from the computer’s point of view. One, if not the main causes of computer failure is too much heat. Which is why, when computers were first used in factories and large offices, the dedicated computer room was cut off from dust and was air conditioned, if not cooled especially. In those days, thirty-forty years ago, computer parts were very delicate and extremely costly.

Nowadays, they are very, very much cheaper but they are still subject to jip from heat. Excessive heat will warp the boards, especially the motherboard because it is large, inside the computer case. They are not built for these gymnastics and sooner or later the very fine connections soldered onto the surface of the board will break and inhibit the flow of electricity. It will die.

In order to inhibit this happening, manufacturers put fans inside the computer so as to increase the flow of air. There are normally at least two in a desktop computer case, one fitted in to the external casing and one directly on the CPU (the chip), which is often the hottest and most expensive single component. In laptops, where air circulation is even more limited, there may be three or four fans.

So, these fans boost the circulation of air within the case in an attempt to cool the chip’s environment down. Therefore, it also stands to reason that there must be sufficient space for that air to flow. If it was left up to the computer to design itself, computer cases would be larger and with more fans. A little like you might like to live in a larger house with air conditioning, if money was no problem.

Now from the human’s point of view. People worry more about looks and fashion and about how much room the computer is taking up. Producers have to listen to what people want if they want to sell their computers. People wanted less prominent computer cases, so producers made half-size cases; people wanted quieter computers, so producers put fewer fans in the cases. And the result was predictable: computers housed in cases like these broke down more often and the only person who was happy about that was the manufacturer.

There is also a trend towards beauty in computer cases. Acrylic, see-through cases are very trendy with gamers. Now games machines are some of the most powerful home computers on the market, because of the power needed to run the graphics at a life-like speed.

See-through cases promote the use of size and fans, because they are often themed, which means that the interior may have green, blue, yellow or red LED’s to light it up. So, for instance, when the DVD player kicks in a red LED comes on inside the case. Similarly with fans, which may also be painted. Some of these themed computer cases are ideal for the chips that reside in them and the individuals that own them
