Windows 7 RC on ThinkPad T43p
Alright, in my philosophy if something new is out there, it is always worth to take a look at it. When I see that Windows 7 RC is available, I downloaded Ultimate version immediately from the MSDN. From my first personal impression, it is far(visual design, multi-touch capability, and efficiency while using resources) better than Vista(which I really dislike).
On my laptop, Windows 7 RC Ultimate works in great performance. Although, I cannot say it is faster than XP Professional, it is adequate to work on. In the attached image, ratings of my ThinkPad T43p is given.
