It's nice to know they do this. When I was using my parent's iPad last weekend I used the keyboard in split mode and it was quite nice except for the B key. It bothered me to no end that it was on the wrong side. While it looks better visually the way it is, I found it odd to type on because of that. If I had known that I could just pretended the B was there and everything worked that would have been great.

It would also be nice to be able to drag the split keyboard up and down. Depending on what I'm doing, it would be nice to be able to lower it on the screen, but that's a pretty minor complaint.
