A year from the official release and Windows 8 is already a great operating system.
It will be a smash hit in my opinion.
Start Menu is now Start Page, it's that easy.
And if you are installing the Windows 8 developer build on a Virtual Machine, don't even think about giving it a fair evaluation. You have got to put it on hardware to see how it works. I tried it on a Virtual Machine and was very disappointed. I tried it on a laptop and was blown away.
Beautiful job on the operating system and the UI.
