I personally am MUCH more impressed with the small laptops (NOT netbooks) using the low voltage core 2 parts like the SU4100 and SU7300. I have an Asus UL80Vt from work (I know it is 14" but all the same hardware fits in a 13" and even smaller - minus the DVD drive of course) and it is powerful and also gets OVER 10 hours of battery life when in use (real world tested)
My dad has a Dell Mini 11z and that thing is a monster as well (and an 11")
