Ive been routinely using it with a Novatel USB modem (Verizon) and USB drives.
I have had my airplane adaptor from my MBPro - totally forgot to suggest it. You will find yourself hanging your MBA over the edge of the tray (or your knees) when you use it tho - it is not low profile like the adaptor. If you have a projector, just get the right video out for it, the MBA comes with both (VGA and Digital)
