Rene Ritchie:

With these latest commercials, Microsoft shows they’re no closer to learning that lesson today than they were back with Bill Gates and the Tablet PC. They’re still mired in Windows and in Office. They’re so afraid of letting go of past success that they’ll take future failure instead. They’ll refuse to compromise on anything other than making the user experience horribly, needlessly, compromised.

That pretty much says it all.
