Today, the majority of houses in Britain have a kind of computer, especially the houses of teens! We rely on computers for everything from socializing or shopping online to check train schedules. However, if you buy a computer for the first time or even upgrade to a new machine, the question is, do you opt for one of the many laptops on the market or do you go to a desktop machine? Both have their advantages and disadvantages, so it comes down to a matter of choice and a review of your needs. One of the main things to remember about laptops is that first they are mobile and, particularly in the case of new models ultra-slim lightweight are easy to carry. This means that with a good extended battery you can work virtually anywhere. Add to this the fact that many places like cafes, hotels and airports now offer free WiFi access, so if you want to go for coffee while you work or need to take your PC with you a business meeting, laptops definitely an advantage over desktop computers. If you’re likely to spend much time on your new machine, then it is useful to consider the design and ergonomics of it, i. e. its positioning on the desktop and how it will affect your posture. It is an argument for choosing desktop computers if you sit in the same place every time you use your computer. Overall the screen is a best height for you, which means that your neck will not be at an awkward angle as you work. On the other hand, there are ways to overcome the usability issues with laptops. Street or the highest good online stores are now selling stands that have been specially designed for laptops. Thus, placing your laptop on a stand and plug in a USB keyboard into it, you can work in much the same way you sit at a desk. This puts less strain on your back and neck and still gives the advantage of having a mobile workstation. Another thing to consider is space. If you have a small work room or study, or if you want your PC to take up as little space as possible, then are probably the best choice. With a desktop computer, you’ll need space for a monitor, separate keyboard and what is usually a fairly large hard drive. With a laptop, everything is carefully packed in a small unit that can store it easily if you want out of sight altogether. The last thing to consider before making your choice is budget. In terms of price, laptops tend to be more expensive than desktop computers of approximately the same specifications and memory. So, if money is a key factor for you, you may decide to opt for the office. However, before making your final decision to draw up a quick list of things you’ll use your new machine, you will most often use it and if it’s important for you to have a mobile machine.
