Re: Bend vs Fold
I would argue that M$ are just making a phone out of the NIntendo DS. It isn't foldable but two screens on a hinged platform. Nothing new really (like everything M$ innovates)
A foldable display would mean the display folds IMHO, not just the platform the display sits on.
Thoughts of a Surface double screen would be echoing lots of other attempts, but a foldable surface I don't see happening. I don't see real world use for a 13 inch laptop with foldable screen, much easier to break and damage etc.
