Welcome to TechIMO.
So far, Dell, Gateway, Sony, Toshiba all only sell Intel while HP and Compaq sell AMD. Personally, I don't think it is the inferiority of the AMD processor that causes them to omit the AMD line from laptops, but the brand of manufacturers. Compaq is horrible and HP is brand new in the laptop business, although appears much better than Compaq (they are both under the same business now, but Compaq still has a ways to go). Now for desktops, I am AMD all the way because of power and price, although Intel is making a strong comeback in both areas.
