Actually I have the Nokia USB charger cable already (I carry it and charge my N810 at work through my office computer). I also noticed that the official Nokia adapter says 100-240V so Im assumning that with the right plug adapter I should be able to use it in Europe (Spain to be specific). That leaves me with just the plane ride to deal with, so maybe those inflight adapters are the way to go.

Now, just need to worry about the iPod :-)
