Ok, I must admit that the most adventure my powerbook has seen is a rough and bumpy transpacific flight - coach class
I know the G3 PBs have graced the Mt Everest Base Camp and was used to log the progress of expeditions. I've also came across websites selling kits for hooking up solar cells to PowerBooks, and of course the hardshell tough cases.
I was wondering if any of you nice folks out there have your off-the-shelf or modified PowerBooks being used in extreme or exotic operating conditions, especially the new Al PBs?
