I have an EEE 1000. (

It's perfect for me, I have to walk a fairly large distance to uni most days and this fits easily in my bag (it's very light too). It's lightening quick, boots up"EEEBuntu" in around 25 seconds and the battery lasts at least 5 hrs on normal settings.
I defiantly would recommend it.
