I'm a college multimedia arts student looking towards a career in my field with a decent amount of travel (eg. field support for a broadcast/media hardware or software company, field engineer for a systems integrator, etc.), and I'm wondering what you think the essentials are for a true 'road warrior'.

(Both hardware ie. Blackberry, EDGE GSM phone, etc. and just 'good things to do' ie. join your airline/hotel/rental cars' club.)

I already have a good ATA flightcase (from R&R Cases) for my laptop, though.

Any advice welcome.
