I bought a 2G eee (700) on a whim, because YES they are INEXPENSIVE.
I think it's a great little machine! But I would recommend AGAINST getting the 2 gig version. Because you will spend a lot of time getting Ubuntu installed - it takes a little bit more than 2 gigs, so you will have to either make your own install image, do some tweaking with the installer or install part of the OS on your flash card (I got a 2g flash card for 12$ and installed /usr on it, sometimes I have to reboot a couple of times because the flash drive doesn't boot in the correct order).
Also don't expect to do a lot of typing if you have fat fingers. I actually like the keyboard, I can get some work done but I always hit the caps lock key accidentaly... Also there's no led to show the caps is on. And I've got some trouble getting the right keymap to get the french accents right, but that's just my local problem I guess.
I modded mine with a touch screen, very difficult but I had fun doing it. I lost a screw and the screen casing doesn't close quite right, but it works, so I'm happy.
So... I bought mine for 250$, I now have a *real*, mobile computer I can take to all my meetings, get email, swap files, get a bit of work done, but if I had to redo it I would buy the 4G model. Also, note that the batteries are only good for 3 hours on the best of days. And you WILL want to mod it/tweak it, it comes underclocked to 600 Ghz, for what is actually a 9ghz processor, etc. etc. The basic Xandros OS installed with it is, shall we say, a bit backwards, but if you install Ubuntu or others you will have to hunt down fixes for the battery, wireless and others.
Anyway, hope that helps.
