reason is simply that Windows dominates the market. Everyone is using the same kind of files, so communication becomes a lot easier. You won't need a top-of-the-line machine for this; just plenty of memory to run Windows (which hogs memory) as well as your applications. As a rule of thumb, count on twice as much memory as is recommended for your version of Windows. For example, Windows Vista wants 1GB, therefore get a machine with at least 2GB. Luckily, memory is not very expensive.

You will need good anti-virus and anti-spyware programs. Everybody loves to write malware for Windows, and if you're sharing many documents and files, you will be at particular risk of infection. Be prepared.

HOME ENTERTAINMENT
Windows or Macintosh are your best options for watching DVDs, playing music, or even watching TV on your computer. Spend your money on a large screen and a gaming-quality graphics card. Processor, hard drive, even the amount of memory is not all that important provided you follow the guidelines for Windows mentioned earlier.

INTERNET AND EMAIL
If all you want is to be wired into the modern world, it's a no-brainer: Linux will give you a low-cost solution. Low-budget hardware, free software: what more do you want?

SOME FINAL TIPS
If you don't see your particular computer need here, or even if you do, just search the Internet to see what software is available! Start with Linux, as that is always your best value, being free. Then investigate Windows and Macintosh. All software should have a list of system requirements that will advise you what hardware it needs to run effectively. If you're buying a new computer, always look for specs that are better than the minimum requirements. This gives you room to grow.

Discuss with your salesman what programs you want to run, how you want to connect to the Internet, and what your budget is with your monitor and printer included. That makes it easier to suggest suitable options for you. Also, try and buy from a specialised computer outlet: you'll generally get much more help and advice than you will in a chain store with a computer department. If it's an Internet outlet, use the phone option to discuss your needs.

Remember: you're buying a computer to run programs! Find the programs that look good first, and then tailor the computer to fit.
