Be aware that a US N810 will have a QWERTY keyboard - this might be OK for you, but if you want a German (even French?) keyboard on your N810 you would need to buy one locally. As for the maps I guess a US N810 will come with maps for North America but maps for Europe can be downloaded free so that shouldn't be a problem. You'll probably pay some sort of import duty I'd imagine, which could make it more expensive than buying locally (factor in shipping costs too) however with the dollar at an all time low that's probably unlikely! It's only a matter of time (days rather than weeks) before the N810 becomes available in Europe. I'd wait a bit longer if I were you.
