Thanks for the replies!
I did some research and found some dual core netbooks. What is better, Atom Z520 or Athlon Neo X2? (Battery is no issue if it last more than a couple of hours). Should I consider Atom N330? (it seems that this processor is near the end of his life)
I'm definetly looking for dual-core netbooks.
Is there any big difference between Intel UMA, Ati HD3200 and Nvidia Ion? are they able to play 720p videos?
thanks again for the help!
