Well, my biggest question is that what are you gonna use the laptop for?
Sadly, the intel processor is cooler usually due to the lower process it is made on. Although AMD's Cool n Quiet is more superior to the Intel.
On battery, the Intel processor is also slightly better but then in realistic scenarios, the difference is less than 5 minutes anyway.
i am just gonna be using the laptop for general uni work, no games (well except apart from a random shot at world domination in stick cricket lol) - according to wikipedia both the processors are same 45nm process, same 35W TDP, clock speed difference of 100 MHz, same cache, but the FSB link on the pentium is 800 MHz compared to the Hypertransport of 1600 Mhz on the AMD. Pentium doesnt have the virtualization for Win7's XP Mode either which AMD does....I still dont get why the Athlon is slower?
