I agree with your performance observation vs Vista, but its only for 1 reason I havent made the change over to Win 7. Its simply because some applications that I was using in Win Xp 32bit couldnt run in Win 7 32 bit and I really really needed them in my pc. Another reason I havent reverted back to Xp is the ironic performance improvement of about 40% vs Xp 32bit even with the aero theme and video wallpaper present. An interesting thing I discovered with Vista x64 is that it is even running some Xp only apps I recently installed 2 weeks ago very very well otherwise right now I would be on Win 7
