I bought an Eeepc 701sd on Ebay for $170. The screen and keyboard were hell to get used to, but it's actually one of the best purchases I've made in a long time. I'm currently travelling Asia with nothing but a small backpack, and if I had brought a larger laptop, I probably would have needed to buy a bigger backpack.
I'm currently running Ubuntu Karmic, (normal, not UNR). The screen feels cramped at times (800x480), but it hasn't been a huge issue. One problem I had was dialog boxes' confirmation buttons running off the bottom of the screen, but then I found that alt+click&drag moves the window.
The 701sd comes with a 8gb ssd, and an internal SD card reader. I got a 8gb SDHC card, but 16gb is still restrictive at times, so I have to run at absolute minimum and clean stuff up regularly.
Webapps can be a bit slow, and flash is a bitch. I can watch most flash videos, but not in fullscreen. Non-flash videos work fine up to about 780p. Above that and the videos start to stutter.
Battery life was nice when I bought it (3hrs+), but now I'm down to about 1.5 hrs on a full charge. Annoying but not crippling.
The biggest issue I've had is with the charger. My Eeepc is about 6 months old, and the charger gave out yesterday. My friend's charger also gave out recently, and he bought his Eeepc about the same time as me.
In summary, I miss the big screen and full-size keyboard of my old laptop, but this Eeepc is pretty much perfect for my needs right now.
Edit: it helps that the girls think it's "cute"
