Good point Cored but when you travel as much as you do, I know how much of a pain it is to haul around all the seperate chargers and cables for your devices.
For my Florida trip I had to bring 4 sets of chargers, including rechargable batteries for my digicam, cell phone, razor, and mp3 player. Part of the reason why I didn\'t bring my videocam along.
And I agree with Sammy 4 gigs is just about right for a week long trip, or daily commute. For my car it\'s nice to have a big library though.
