I always go on (and on...) about how I chose a 12" powerbook because it was really portable and had decent battery life. Thinking about it, it isn't that much more portable than a bigger powerbook or macbook, but it has better battery life than those with bigger screens. Now that I have a new battery in here I have to gush about how nice it is to have really useable battery life. Last night I watched a film (well a long TV episode) on battery power, listened to about an hour of radio paradise over wifi, and then here I am this morning, blogging, surfing and doing some web development and still have a third of my battery left. All this time i've had wifi on, screen at full brightness and about 10 applications open.
