I've not used the 12.2 w/Hancom much other than to open a few existing documents and see if formatting held up from Office 2010 which I use at work. Formatting was the same, by the way...So that's already freaking awesome. I can see myself using this to type lessons on the go, typing a newsletter, and transcribing meeting notes. Other than that, I really don't do much typing away from my laptop at work. The on screen keyboard is really very good. I've not connected my BT keyboard to it at this time, but I have one of the old Logitech keyboards for Honeycomb I use with other devices.
