1) UHK without the palm rest is pretty small keyboard to carry. Mine is with palm rests (because I've started feel pain in wrist so invested at the max). But had no problems bring it back home with latop from the office while commuting on bike. I've used old padded sleeve of 14" laptop as a case. 2) That was the reason why I've picked UHK - it is open source. Parts can be easily replaced. Though it does not seem it is going to break soon.
