Really, this is arguable. The Turion and Pentium M are pretty close in performance, and the Pentium M's battery life beats the Turion 64's by about ten minutes. The Mobile Athlon 64 is also about even in performance with some Pentium Ms, however, the battery life absolutely sucks, and runs very, very hot (and I say this from personal experience). But the Core Duo that Intel introduced is quite powerful. I'd like to see how AMD is going to respond to it...
