Has anyone tried using this with an iPad + USB connection kit from Apple? How's the power draw? Most keyboards are hit & miss for me (Poker draws too much power, and so does HHKB 2 Pro. Older pre-shine Ducky on the other hand works fine. Matias Laptop Pro is fine over BT but rather chunky). I would get this in a heartbeat if it would mean I could reduce my mobile hardware list to just a 4G iPad and an Atreus.
