i played around with my friend's 1.5 year old model and toyed with one in the store (officedepot) before i bought the sharp av18p (6 months+ ago). on the averatec:
the keyboard layout sucked pretty bad. the backspace key on the store model i messed around with was the worst thing ever, it was the size of a postage stamp. they have some really weird home/insert/pgup/pgdn configs, ive never seen it like that before (they're all smashed together). flex on the kb was not good at all. ON THE NEW MODEL, however, they may have fixed all / some of these complaints, from what i can see in the tom's hardware review:http://www.tomshardware.com/mobile/20040610/index.html
the directional pad and all the buttons in the top right still look scrunched like crazy, those things are hard to use if you have big fingers.
using extended desktop with the new model is probably not a good idea, a high refresh rate at higher res makes for a blurred screen. performance is really not-so-good. tom's shows pretty terrible graphics performance on the new one, and the old ones i've messed around with were pretty much only good for websurfing / word processing. battery life is sub-par too, under 2 hours. my sharp could get 2:45 most of the time for everyday stuff. on the durability, my friend threw his in his backpack everyday with no sleeve to speak of, so it was pretty beat up; the exterior scratched REALLY easily. it seemed to be still working when i saw it (that was about 1 yr of use), though.
Anyway, I'll go with Tom's on the conclusion:
"Due to its excellent price-features ratio, we rate this notebook as "good," although just barely.
awesome price for an ultraportable, just don't expect to do too much with it.
