I also use a Motion Computing pen with pretty good results. Actually I find that if I don't look at what I'm writing or stay ahead in my brain with the stylus hitting the screen the writing comes out rather well. Don't know if that makes sense. Agree with the USB ports and to trying to plug in external speakers while using my Motion keyboard. Can't do it.

BTW I'm also a fountain pen aficionado. I wonder if there are certain "traits" that make an Edge user?
