Bring along a very short (6- to 12-inch) extension cord so you don't take up multiple sockets on a power strip.
USB charger for your cell phone
- Two blank CD-Rs
- DiskWarrior boot CD
- Kensington FlyLight USB LED light
- Kensington security lock (I've never actually used it--instead, I just never let my bag out of reach--but it's a good thing to have on hand)
- Cables (camera to USB, camera to TV, FireWire, Ethernet, and RJ-11)
- Adapters: mini-DVI to DVI, and mini-DVI to VGA (for connecting to projectors and other monitors)
- Handeze gloves (In case I need to do a lot of typing while traveling)
- Antibacterial hand gel (essential at any conference where you'll shake hands with lots of people and then touch food)
- Fairly large plastic bag (to act as backup rain protection)
Use a PDA when possible
Date your battries
There's an alternative to lugging along a second battery on long flights--booking a seat with an AC outlet. Such powered seats are turning up more frequently on newer planes, particularly in first and business class. But how can you tell whether your seat will be powered? Before you select a seat, find out what sort of plane you'll be on, and then check SeatGuru.
