name me a laptop with kickass battery life

I'm planning on eventually getting a new laptop to replace my beat up (not to mention airport stolen) toshiba satellite. Mainly because id rather not pay for a new battery (which lasts roughly 15-20min).

ibooks, and i asume macbooks, seem to have good life. but are expensive as hell. OSX or Win doesn't really matter considering the apps i use. I only need this for webdev, maybe a movie here and there, and photoshop. not for gaming. but mainly id like to have something that doesnt die on me after an hour or so.

Can you FAIL HARDER???

A laptop is not a web browser durrrrrr

OP: Look for a laptop that lets you have two batteries in it. Many times you can replace the cd with another batt. Dells and IBMs have this, I think. Those little tiny Transmeta Carusoe based laptops (I forget who makes them) were supposed to have extra long battery life. Tiny laptop is tiiiiiiiiiny though and they sux cox to work on.
