I have the 12" powerbook, and personally I would like the backlit keyboard. From what I've seen from the two buttons that actually do light up on the 12" (the caps lock and I think F6), I think it would come in rather handy at night. I know when I'm tying away I never look down at the keyboard, so most of the time it isn't a concern. However, when I actually have to find something other and I don't have my hands in proper typing position, it is a pain. The only problem is, it's pretty tough to test out, even in the apple store since the lights are so stinking bright. I would be interested to see a picture of it in action though. I think someone needs to get on the horn and do that. Take a picture with the screen light off, and the backlight on, so we can see what we're up against here. I'm actually somewhat suprised that apple doesn't have a picture of a nice 15" glowing away on the website. They're missing out.
