The phone version works but the res is bad and in landscape the keyboard takes up most of the screen. Shapewriter works a lot better, but I still find the dragging too annoying on a large screen, its manageable in portrait though. I personally like swiftkey tablet beta and thumb keyboard tablet beta the most so far.
I like the theory of swiftkey, but I find that it is too large and the placement of the backspace key is very annoying for me. Also no tab key. In like the thumb keyboard beta, but it needs a full layout for when you are typing on a flat surface.
