Should I get Windows XP, Vista or Windows 7?

[Munch]

People say XP's insecure...I've not had a single problem with XP and I've had it for like years...same copy, too. And even worse, it's not a legit copy, so it had even more of a right to behave badly, but it never.

XP's not insecure, W7 is just more advanced so it makes XP look small and insecure (as that's what XP is to W7).
