THE BEST way to define a Surface Product :

"The one thing I think most people don't get is that it's not supposed to be a better tablet than the iPad and a better laptop than a MacBook

It's supposed to be a better laptop than an iPad and a better tablet than a MacBook, and it absolutely excells at both and still being a single device."

I saw this comment on WPCentral and this guy really nailed it. It makes perfect sense!
