I've seen Vista come by, and while it looked cool, I assumed that it would run slower on my machine with the Aero theme. I also run my XP with animations, shadows and the like turned off, and also set to Windows Classic theme.
With Windows 7 on the horizon, is there any reason I should be thinking of upgrading?
Update
To clarify, I turned off the animations to get better performance.
My computer is about 2 years old, and is running these specs:
Intel Core(TM) 2 CPU 6300 @ 1.86GHz; 1 GB of RAM
Update 2:
I now run Windows 7. :)
