I'm looking at purchasing a new laptop for business. Battery life is the biggest concern. I'm trying to decipher which Intel processor is going to give me the best battery life. Speed, cache, FSB, etc. are all unimportant compared to Battery life. I have to admit, I got a little lazy, It wasn't easy for me to find the tech. docs on some of the processors. I'm hoping someone here maybe knows off hand. Thanks.
