Narrower bezels will be implemented, remember these were only preliminary concepts It is possible and we want it too. Bezels should be as slim as possible, taking into account that one needs to be able to hold the device as tablet too. IMO a bit slimmer than Surface is optimal.
The Origami-style keyboard is cheaper & easier to manufacture than a kickstand solution, which inevitably adds a bit to thickness. Origami, though, has its drawbacks:
1) Only 1 angle - what if you need another?
2) Tablet use only - no stand? You always need the keyboard then..
Do you suggest kickstand + Origami?
