Web OS vs Microsoft Tablet

A lot of people have given Microsoft criticism for their slow response to the iPad. But today the New York Times had a very interesting article on WebOS and it total failures. Microsoft has bet the the next three years on Windows 8 and its tablet features, but it has not rushed its development environment and application base like WebOS. When I pulled up the first Javascript application in the Windows 8 developer preview it had the same problems but Microsoft has bet big with Metro. With Windows 8 you get a unified UX from a PC, tablet and phone. Can Microsoft succeed where HP failed.
