dont use XP. It sucks
That's like saying "Don't use Athlon, it sucks", or "don't use Intel", or "don't use the Internet", or don't use IRC!

Every piece of hardware and software has a purpose and task that it's best suited for, and some people prefer one to the other. I value and respect the opinion of others, as should you. I get offended, however, when someone makes a comment such as this.

I "prefer" to use Windows XP and as far as MS desktop OSes go, it's the best yet. However, I wouldn't use it for everything. Just because you may or may not like something about it doesn't mean that it sucks. There are plenty of things I don't like about it, but overall, it's a very nice OS.

There are tings I don't like about Linux and Unix and MacOS, and NetWare, and so on, and so on. That doesn't mean they suck.
