Windows 7, Milestone 3 was just previewed and Mary Jo Foley got a brief look at it. And though Microsoft is now just one more preview away from the official Beta 1 version, not a whole lot has changed from Vista.
We should see a Beta 1 release of Windows 7 sometime in December, with the operating system itself dropping in late 2009. We should be seeing just about all of the features that are to be included in the beta in these previews, yet not much has changed since Vista. In fact, it seems much more like an add on to Vista itself than a brand new OS.
Windows 7 seems to feature the Ribbon UI from Office 2007 in other programs such as Paint and WordPad. At the very least, let's hope Windows 7 is more stable than Vista and perhaps has a few tricks up its sleeve.
