It's no XP killer. That's for sure. Microsoft alienated users with Windows Vista. Now they are alienating developers and MCSE's with Windows 8.
The tile interface is kind of lame for desktop and laptop users who use a keyboard and mouse. They hosed the File Manager with the stupid Ribbon, like they screwed up Office 2007. I still like the iPad interface better.
MSFT stock is looking good, but it looked good when Vista was released too. I say sell MSFT on the hype. This stock won't stay over 30 for long. Sell before it's too late!
