I wonder why almost every topic on this part of the forum have to turn into 'mine is bigger' contest.
There is no use debating which OS is better to use, as there is no use debating which arranger is the best on the market.
Windows Vista might work perfect for some users, but majority of them are not satisfied with it. Microsoft realized that, and that's the reason for prolonging Windows XP sale and support, as well as hurrying up with the development of Windows 7.
As for the Windows XP and OSX, XP was always considered to be unstable and vulnerable OS (although with vast software support), while OSX was synonym for problem-free easy-to-use OS (although it was running on quite expensive hardware, and had much fewer applications for use). All this of course doesn't mean that if You choose XP you will have constant problems with you PC, or if You choose OSX that you will not have problems using your hardware and software.
In order to find what's best for You, You have to try all the possibilities by yourself and then make decision, because what's best for me, might not be good for you.
