Title is slightly misleading.
Sounds like AMD do want to add performance to a thin form factor, they want to price it in a large audience however.
Though my opinion on this is, if you want a highly portable laptop, the best you're gonna want is internet/word processing.
If you want to do graphic design/gaming, you're going to have to forgoe the slimline and battery life approach, and will most likely need to be plugged in (ugly adapter!)
Currently, without using a discreet gfx card (obviously chews up space), AMD have the lead graphically with Llano chips.
One last thing, gaming and apple, lul.
