The powerbooks can dual head which is in my eyes brilliant means i have a tiny wee 12" powerbook

I take it out and about i have tiny machine, i take it home plug in the external machine i have huge screen for most stuff and laptop scren for mail or something else i want to keep open but not bothering me on the main screen. i also have the bluetooth keyboard and a microsoft bluetooth mouse which is great as you just put the laptop down and it instantly picks up the keyboard and almost instantly the mouse dependant on how playful mouse is feeling
