I looked breifly at a M1210 at a dell kiosk in the mall. The Sony looks better. The Dell had so many lights it looked like it was ready for Christmas and it was so thick. I am now holding out for an Asus S6F or a dual core Sony TX. The Solo cores are already out by the way.

Either that or a better version of the Macbook hopefully comming soon.
