I'm not quite a Bedouins yet. My main computer is still a desktop where I do my work every day. My laptop (IBM T60 if anyone is interested) is always on and it's the computer that gets my crayon e-mail as it's default.
When I go on the road I'm always worried I'm not going to have something that I need. So, a little something that I've learned that helps is the day before I leave I only work on the laptop. That way if I realize I don't have something I can just go grab it off the desktop BEFORE I'm hundred of miles away from it.
This has saved me numerous headaches from a hotel room somewhere in the world. I figured it would be worth sharing with everyone.
