- You can only see the front ~half of the computer in this image. There's yet more computer behind the screen and keyboard. (This photo is a side view that makes it more obvious.)
- Much of that volume is taken up by the sealed lead-acid battery.
- Yes, that means this computer was heavy as fuck. It was nicknamed “the Luggable” for a reason.
- The trackball could be swapped out for a ten-key. Of course, System 6 was impossible to use without a mouse, so that meant you had to plug an external mouse into the ADB port.
- The initial model didn't have a backlight—if you could read the screen in ambient light, great; if not, too bad. A later model added the backlight. (All PowerBooks had it, but some PowerBooks' displays sucked for different reasons.)
