One thing with travelling a lot; you quickly appreciate the simplicity of USB as a generic charging technology. I don't need to carry several adapters in my already bulging luggage, and with one charger I can now provide power to my phones, my iPods and my voice recorders.
If I fly through Columbus Airport, I don't even need that charger...
The laptop stations at the gates offer USB power along with standard mains outlets.

Now that's what I call quite useful.
