The following is a showcase of performance differences between an Intel based Atom netbook and an AMD Bobcat C-series based netbook. I will take ANY DAY an AMD solution over an Intel one. Atom CPU's preaty much made me stay away from that market segment, I was hoping that AMD would have something better than what Intel had to offer, my waiting is over, thanks to AMD.
The reason to as why anyone would want to get a Netbook, is because of it's weight. As a student, caring a Notebook around school from 08:00 to 18:00, is a pain. So a netbook for that market segment, fits the bill.
