CNet's got a decent overview of the upcoming mobile offering from AMD. Looks like the Turion will possibly run quite a bit cooler than the current generation of A64 notebook chips, & be comparable as far as battery life with the Centrino.

"Notebooks sporting the new processor will come out at the same time as the chip, he added. Turion notebooks will be marketed for the consumer and business market. The company will also continue to produce the Athlon 64 mobile chips as well as budget Sempron notebook processors."
