I know you are drinking a lot of Kool-Aid but if you think Microsoft have a chance at the next generation of PC, I think you are just kidding yourself.
The stage is set for the next 10-20 years, it will be dominated by Apple and Google with Microsoft as also ran if they are still in this space. Please don't get me wrong, I LOVE Microsoft products from Xbox to Windows Phone. While it is true that the market is still growing for tablet and mobile, people are going to the brand that they know about, one with plenty of Apps and great track record or good price like Google Android.
Microsoft is very late and the players already carp out their space, but it won't be anything more than 1/3 of market. I would be happy just to see people not making funny face when I told them I have Windows Phone and glad if we can get to 10 percent.
Pricing is way off on the Surface, especially the RT, unless on the 26th Microsoft could unveil that it has all the Apps that are on Androids and iOS. No consumers is going to wait for their tablet to catch up, just like no one is buying Windows Phone because quite frankly it is just behind the curve.
I hope I am wrong, because I want to use Microsoft products for many years to come but the pricing on Surface, the slowness of Windows Phone 8 just doesn't show me that Microsoft finally get it.
