So far, so good.
Ok - the pinned application section in the task bar... is... freakin'... cool!
Not only is it at the window level, but for Internet Explorer, the tabs are displayed individually.
And one thing that my boy Donn brought up starting back in Vista was the "Start and Type" search functionality. I use Launchy in my XP machines for the same features/functions. In Windows 7, the search results are expanded. The term "virtual" gives me options from Internet Explorer, the Virtualbox application, and the Virtual machines within Windows 7 - such as the "free" Windows XP machine.
The extra wallpapers are really nice.
It's about time more (free) themes are readily available for Windows 7 directly from MS.
I'll keep trying... but I will keep seeking the fault. It ain't wrong.
