I've used both, and other keyboards on previous PDA's, gotta say the think outside one is the best i'vr had so far, once you get use to the multiple function keys to use numbers etc

Certainly the easiest to write reports and general stuff, the keys are well placed and it's very sturdy. Only complaint (if i'm being picky) is the lack of extra supports on the edge of the keyboard. if you hit one of the keys on the edge on the board to hard it can move the keyboard (little tip effect) as the main body is not supported properly. Although it is very rigid so is not really detrimental to function, just a little annoying.
