I just installed Windows 7 Beta on my PC. All is running great. The reviews by the tech press have been very good for this OS and I add that they are well founded.
I love the new features. The OS is snappy and visually stunning. The full release of this OS is expected this summer, although delay rumors abound as usual.

My hat is off to the Windows 7 team!
