I don't understand the "OMG MICROSOFT MADE A TABLET IT IS CLEARLY COPYING THE IPAD" reaction Microsoft's getting here. They're absolutely ahead of the curve with the blending of mobile and desktop operating systems, something which I am extremely happy they are doing, and this is absolutely the logical design choices someone in that position would make. Yes, it's very similar to the iPad in many ways. But other than…
I don't think people realize how big this announcement was.
Yes, MS is still a multi-billion dollar company and a good portion of their revenue is likely secure for years if not decades. But we are at a key juncture in computing here, as important as the mainframe/mini-computer to PC transition if not even more so. And if MS had just blundered on and made half-assed token efforts they would have forever set themselves into the wrong gear and they would have relegated their company to a different market and marketshare than dominating the mainstream PC market as they've done.
MS has made a big play, and it may be enough to keep them in the game and revitalize their brand image. Time will tell.
