This guy seems to think that MS is trying to sprint to the finish line, but MS has always been the tortoise not the hare. Windows 8 and the Surface RT where just step one. Win Phone 8 and Surface Pro are step two. MS is trying to get PC users to get used to a mobile like interface. The general public who buys Dell and HP are all slowing converting to Win 8 and they will get used to it. When they decide to go buy a smart phone of a tablet they will already know how to use a Win Phone 8 and a Surface RT/Pro. Having the exact same interface and apps on all your devices is huge and will be what wins the race.
Oh and Bing is growing slowly as people realize it's better for searching and maps. XboxNext will almost definitely be a Windows RT machine with the desktop locked out so that yet another device that people will already know how to use since they learned Win 8 on their PC after buying a Dell.
It's a slow burn, but that's what MS does and it almost always works for them.
