PC Mag just released a review of Office 2007. They gave Office a 4.5 out of 5 stars.

I love this quote: "Once you get past the few minutes needed to navigate the new Ribbon interface, you'll wonder why Microsoft waited so long to get so many things right. " 

They didn't cover Access in this review and actually missed the point that Access has the new UI. 

“The new interface doesn't force you to rethink the underlying logic of your work, because Word, Excel, PowerPoint, Outlook, Publisher, Access, Project, InfoPath, Visio, and OneNote all work basically as they did before—only more easily. Word, Excel, PowerPoint, and Outlook are the only programs to get the full interface upgrade. Actually, Outlook gets the new interface upgrade only in its content-creation screens.”
