Yeah. I'm actually completely in love with my AAO (and I even store my music on it, since I got a HD). There's nothing I need a full blown computer for, and if I really need the screen estate and keyboard, then I just use external ones. I've written a huge amount of code on my daily bus ride.
I use my desktop keyboard, a Happy Hacking Professional, with my netbook. Both fit in my standard laptop backpack with plenty of room, and then I don't have to compromise on the keyboard. (The small screen doesn't bother me; xmonad makes it easy to deal with.)
