By bending backwards, do you mean sitting on a adjustable stand? The new ones do come with a stand that collapses on to the surface's back when you're not using it. It's attached. And I should correct what I said originally. I use the surface pro (tablet). Surface book is a full blown laptop.

yea i had a surface pro laptop for work, but i couldnt bend the keyboard behind the screen, so when i had to do work it was kinda. awkward with my keyboard in the way. I just wanted to know if the newer versions can let u do that or not!!
