I liked the folder layout. Much more intuative.

Aero glass is good. Much better then Luna for XP or Classic. It's about time Windows had some built in bling.

I really want to like ReasyBoot. Unfortunately since my T41P is my primary machine (having displaced the Ti), I do not want a USB flash drive sticking out of the side of my laptop. Rumor has it that ReadyBoost does support 32-bit Cardbus (not PCMCIA which is only 16-bit). The trick is you need one of those 'high speed' compact flash cards. I got the cardbus adapter and am now searching e-bay for a high speed 1 or 2gb card. Then I'll give it shot. If to works great, if not, damn.

Overall it is reasonably fast. I am hoping for better drivers for my Thinkpad. Specifically for the power management, ATI FireGL T2 128 GPU and wifi. For some reason wifi is ridiculously slow under vista.

I do not like the Windows Sidebar.
