Windows xp is no longer gonna be available after June 30, 2008. But I read that if a computer store still has copies of XP, or machines with XP installed they can still sell them as long as they please. Computer companies like Dell and HP will send you a disc of windows xp if you are not happy with Vista and want to go back to XP. All you have to do is call them up. And you can do this after the June 30th deadline.
I think people will take advantage of this, for those who are not happy with vista they will want to go back to xp. Alot of people are more happier with xp, my mom has vista and so far has had no problems with it, but she dont get on it ofter either maybe this makes the difference. I think its cool that these companies are doing this at least it gives the customer the choice if the want Vista or not and not just forcing it on them.
