Express card? No interest. Why widescreen? Because it fits on the keyboard. You can either use widescreen or have a lot of blank space on the sides of the screen. It's the same ratio as the N8x0. I have a 701, and I use it for almost everything, seldom bothering to turn on my desktop or full-size laptop. My N800 doesn't get a lot of use, mostly on the road with Maemo Mapper, and sometimes from my pocket, but the Eee is so portable I tend to take it just about everywhere I would take the N800.
