He may trash Vista in the article, but WSJ tech author Walter Mossberg enjoys his experience with Windows 7. He mainly boasts about the usability of the operating system, and how it finally gives XP users a reason to abandon the now 8 year old operating system. Despite seeming to be somewhat of an Apple fan, I've never read his articles before, Mossberg mentions he feels Windows 7 beats out OS X in terms of taskbar and window organization, as well as touch features.
The real question, and one that I've felt was answered for me in my testing with betas, was whether Windows 7 was faster than Vista in terms of booting, loading applications, etc. PC World seems to think not, particularly in terms of loading apps. Performance within the applications, however, once they were loaded seemed to improve with 7. I guess we'll all just have to see for ourselves October 22nd.
