Anywhere I go:
--iPad 2 w/ Kindle app, music, videos, iBooks, TripIt.
--Etymotic HF2 Headset (high attenuation about as good as active cancellation) for the plane.
--AKG Q460 headphones for the hotel.
--Asus WL-530g Mini Router flashed with DD-WRT, OpenVPN (StrngVPN subscription).
--Panasonic LX5 camera.
Depending on where I'm going, I also take the Sony ICF-SW7600GR mentioned above, and a Princeton Tec headlamp.
