Wouldn't it just make sense for the Surface Pro 5 and the Surface Book 2 be the same thing? Really, I love my Surface Pro 3. I especially love the kickstand so that I can fold the keyboard up and have it take up much less surface area (no pun intended) on my counter. The only thing it really needs more than anything else right now is a performance keyboard with dedicated graphics and a bigger battery to power it. So why not make one for the new Surface and not do a Book at all? Seems like that would be the most innovative thing yet....and no wacky hinge.
