I just like Windows, my XP has yet to crash and Ive had her at least six months. You can take care of your box and it should be ok. I have no illusions that this is due to the relatively low technical usage my XP gets so ultimately from a home user point of view with a few technical interests Windows is nice.

From a security point of view perhaps not.

But you state you dont like XP because it is slow as hell...
