Instead of wasting ours and their time and money, they should round up all these new features and put them in the next Service Pack for Windows 7.
Technology hasn't jumped enough yet for a whole new OS when Windows 7 hasn't even hit the same stride as XP did about 3-5 years after its release if Microsoft is saying that Windows 7 is the "XP Replacement".
A few things that need to happen before we will need a new OS are:
1. 3D without glasses
2. Higher video refresh rates
3. Higher Anti-aliasing
4. Monitors with built in motion/eye detection
5. SSDs become standard(of course after they become cheaper)
6. USB 3.0(4.0, 5.0 or whatever) becomes standard
7. PCI Express 3.0 comes out and becomes standard
Just my humble opinion
