From what I've read so far, the only advantage that Vista seems to have over XP is that they're redesigning the UI or something. I don't care about that at all, and disable all the cute UI animations and effects. I want power, not stuff to take away my power.

I've also read somewhere that Vista is a sort of "in-between" release, very much like W2K easing user transition from Win98 to WinXP. Supposedly whatever comes after Vista is the sh*t. Also, if Vista uses the same code base as W2K (as XP32 does) then there's even less incentive to upgrade.

I still use Windows 2000 and I like it because it's streamlined (read: less fluffy features) and I have been seriously considering going Linux.
