Hi, I made this video. I don't show it in the video but this is a Touchsmart TM2. The screen flips up and swivels 180 degrees to reveal a conventional laptop form factor with keyboard, so I mainly use emacs that way. However, gestures are still available above the keyboard when the screen is in that mode, and also emacs code reviews that i talk about could be interesting... I have a lot of other stuff planned, see http://lispgamesdev.blogspot.com/ for more.
The editors I've seen for iOS all have issues with special characters so I had been really curious to see how the emac folks would deal with that. I was pretty disappointed when I found out they didn't.
The gestures were pretty cool anyway, though. From what I could tell, they seemed pretty intuitive, too.
Slightly OT: anyone know of attempts to port emacs to android? If I had that and an attachable human-size keyboard, I could ditch my laptop for many purposes.
