Martin, keys on Yoga retract when you start flipping it more than 180 degrees and there are rubber feet specifically for that (laying it flat). Believe me, they put a lot of thought behind it. Oh, another thing, there is also a pen that is built in the body, so you can use that too, if needed. As I mentioned, I had both Surface and Yoga I sold Surface second day I got Yoga and never looked back. But hey.... it is just my opinion smile
