This is basically what I did with my Acer netbook for a few years. I threw Arch Linux on it and used it through most of college.
With the largest battery I could find for it, it easily got at least 10 hours, IIRC. I don't believe it approached 20 hours, but this was also about 7-8 years ago.
I don't remember the exact model (it was one of the later ones they made, I believe). I have it around here somewhere if you really want to know which one it was.
The worst part about it was the screen resolution. It was something like 1024x600. There were a few applications and light games that assumed your screen was at least 768 pixels tall (Photoshop CS2, for example, which otherwise worked perfectly in WINE).
For something a bit more modern, I'm continually intrigued by the GPD Pocket Mini Laptop [1].
