I don't think so. (If you want my opinion in detail, go read http://www.techradar.com/reviews/pc-mac/software/operating-systems/microsoft-windows-7-622923/review (all, eek,11 pages of it - I had a rather sweet email from Microsoft this morning calling it "incredibly thorough") and our view for business is at http://www.itpro.co.uk/613588/windows-7-rtm-review).
But when it gets down to spin and questions of trust and intent and all, I love this quote from Charlie Owen (recently of the Windows Media team, now over on MSDN and similar Microsoft properties), which balances neatly on the edge of Occam's razor
"In case there are some of you who still think Windows 7 is on a schedule similar to prior versions and everything you've read to date from Microsoft on the subject is just marketing spin: When have we *ever* been that great at marketing?"
