It was a breath of fresh air compared to Vista. All the Aero UI changes are very noticeable. Taskbar/Title bar remains transparent when maximized, Flip 3D is 100% faster, Snap to borders, Window shake, Taskbar previews they are all amazingly well done. The side bar was removed for a better gadget-based interface which gives more desktop room.
But the best feature that really made this version of the OS better is the configurable User Access Control (UAC) which was the most tedious thing in an operating system since Windows ME...
All in all, after using Windows 7 for just about 10 hours, I give it my thumbs up and I recommend it to anyone.
