I have an eee900 - 9" screen, 1GB RAM, 20GB SSD & linux. I think it's a great piece of kit, but it's not for everyone.
It's ideal for what I want it for, small and lightweight, boots quickly (45 secs, even with the full desktop enabled), all the wireless gubbins works a treat, and the screen is big enough to be useable, and bright enough to read in sunlight, just.
It's not all ham and plaques, though. The battery life on this model isn't great (2 hours away from the mains, if you're lucky), and the keyboard isn't that nice to type on if you have fat fingers like me. The whole build quality of the eee is also a little Fisher-Price, but then again I wasn't expecting too much for the money.
There's a load of competing models that've come out since I bought the eee, and reading the reviews they all seem to compromise in one area or another, but that's kind of the nature of the beast. No one's yet made a netbook that can be all things to all men, fit comfortably in one hand and come in at under £300. But I'm sure they're still working on it..
Cheers,
