Been using one of these laptops quite a bit recently, the S03SE version so has the A8-4500m + 7670M.
Very impressed with the performance from this, and thats with the lower shader count on the A8.
The display isn't much use, but for very portable gaming it does the job!
Very much looking forward to AMDs next APU, Trinity is a very capable chip.
Edit: Absolutely essential to get off of the stock Samsung touchpad driver though. Absolutely horrendous!
Updated to the most recent from the Synaptics site, finally the multitouch functions work properly...
