That's what I was thinking, because Vista is definitely coming out within the next year, and it has all these hardware requirements. I also don't have want to have to buy a new XP2 just to end up buying Vista a few months later.
It's just that right now, my PC is driving me insane. It's only an Athlon 850 MHz (it's an old replacement bought 6 years ago) with 256 MB RAM, so it's really hindering my application use, not to mention EXTREMELY slow (it takes like 15 minutes to Auto-Run a CD, and that's not an exaggeration). I've put up with it for a year now, and I just want something a little more modern. I'm sure it's not virus or spyware related, because I rigorously run lots of security related applications (one of the reasons why it's slow).
