"The A-Z format that they are using is what has been used on the iGuidance Pocket PC version in the past. I think they are just standardizing all the versions."

"I just installed iGuidance 3 on a PDA and I see why QWERTY could be a problem there. On a PDA even in the landscape mode you could have difficulty fitting 10 keys across the screen from left to right. That's what QWERTY has in the top letter row :-(

I guess it comes down to what is more important: the convenience of the familiar QWERTY keyboard or the size of keys. Most users would likely soon complain about too small keys than about the non-QWERTY OSK."
