I think the clicks has some potential but only in bed where you can tuck it ontop of your tummy. The grip strength needed to support the device is awkward with index fingers bearing the brunt of the weight on the back and the pinkies jave to manage the rest unless you use the palms, but the edge keys are hard to use. It is definitely a hard tool to use in a pinch. 
I do think portrait mode is the weak link for weight balance, but i do like the device in landscape. Unfortunately , Apple hates it.
One thing I do like is that the shift and symbol keys do not need to be held to affect the next character. The cramping was insane.
