One of the main problems with Windows is that it is insecure. You put it on the Internet and you can bet by the end of the day you will have spyware or a virus installed. It is so bad that it has become a full time job for most IT guys like me. Sure companies will take your money and sell you anti-spyware or anti-virus software, but why not just get rid of the holes in the program so hackers can't abuse the OS. With Linux I have yet to find a hacked computer. When there is a hole in a program (so someone could exploit the OS) it usually gets fixed within a few weeks. Why has open source software (Linux) become better than what one company (Microsoft) can produce. The basic concept is that the more people who are looking at something, if there are bugs to be found, then there are more people fixing them and finding better ways to do things.
It has the Best Software
This might be a little over the top because I have used some great Window's programs, but it all depends what you want to do. For me, the main program I use is Firefox (an Internet browser). Mozilla makes it run in both Linux and Windows XP so there really is no difference here. For me the best program, which you can only get in Linux, is Clock, made by George Lebl and Gediminas Paulauskas. One click and it shows you which day of the month you are dealing with. Slick! A lot of people who use computer software want to use the "best" software or at least software they are use to using. Why? Time is important! People would be happy just to tell their robot to d it for them, but no, most information exchange requires humans for it to be important to humans. :) Other great programs: Open Office (Word Processor), Gimp (Draw & Photo Editing), GnuCash (Accounting) plus a lot of great games -- all these programs are free, only for the downloading.
Linux has been running 64 bit programs for over 3 years now. Window Vista is just getting into the groove.
