The play and Charge kit, if I remember correctly, doesn't transfer data over the cable at all, and it still requires the wireless receiver to be used with windows.
Also, i know all too well the annoyances of playing games with the dpad, and just how finicky it can be. But for text editing, I'd prefer having more than the current left and right arrows. I'll try and figure out xpadder after work today, but i like the toggle ability present in the drivers, and don't want to give that up.
Thank you for the reply, and as always, keep up the good work.
