First hour impressions:
-Dat font rendering
-Holy shit the icons all fit the theme!
-Whoa, no window borders=sexy
-The start menu is an unsubtle combination of old and new
-Wait, where the FUCK are my categories and columns for tiles? Organization= destroyed
-Holy shit make that search and app switcher icons be optional
-I have to install drivers to use my touchpad for more than clicking? Da fuq? MSFT plz this works out of the box in a Linux OS that's still in beta
-Whoa, bootup is fast, as I had to found out after installing touchpad drivers. Even faster than Win8.1. Seriously, that was almost as fast as the Linux distro I was using. Like not even noticeablely different.
