Stop the presses! Bill Gates says he loves the Surface tablet

From Microsoft:

"Microsoft's Chairman Bill Gates chats about Windows 8, Windows Phone 8, Natural User Interface and Microsoft Surface."

In a Microsoft sponsored video, Bill Gates said that the Surface is an “unbelievably great product” that Microsoft delivers “an even better tablet… that also has what you’d expect in a PC.” Bill Gates was also praising the device for it`s “richness of the swiping” and that it “takes the touch interface to a whole new level.”

this is unexpected? what exactly is "richness of the swiping" can you get it in decaf?
