The action center pops up an awful lot of messages, by the way. I thought Windows 7 was supposed to be less 'noisy' in the notification area?

Not a big fan of the show desktop icon placement to be honest. Other than that, first impressions are good. Testing...
The theme control is very smooth. Start menu smooth. Performance good.
I can't hide running applications from the taskbar. That'd be nice to have. There's some annoying applications that are supposed to just run in the background but do not minimize to tray.
