just got this and love it. mine was badged a C-50 but was pleasantly surprised when CPU-Z said C-60. underload I confirmed it turbo'd to 1.33 GHZ, since this an APU the ATI graphics side also gets a significant bump in performance with the ability to turbo from 276mhz to 400mhz(6290 performance). this thing can play 720p mkvs all day. The battery life on this thing is impressive! It has all the stats you could want in an affordable netbook, imho.
for the price, I don't think it feels cheap at all, the LED screen hinge seems nice and tight and the keyboard and trackpad are decent. yes the trackpad button is a little weird and requires more force then it should, but I am guessing it will work itself in. I usually use the tap method on the track pad itself for most "button" tasks anyway. I didn't thoroughly search for it but my only complaint is no HD light, but there are on screen apps for that....
did the demo have a battery in it? sometimes battery-less demos give an illusion of cheapness since they are so light then...
