I live in EU and my battle.net account is set in EU.
I'm going to be on during some days in NY, so I was thinking in buying the game there (US).
What happens when I go back to EU and I put the key in my account? Can I download the EU Client? Or my key is linked to the US Client?

Diablo 3 is cross-region. It's the same as Diablo 2 and StarCraft 1. You select the region in-game and can create characters on that region, and change at any time (characters aren't available cross-realm). It's not like SC2 where you need 4 versions.
So, whether you buy the US or EU version, it differs not.
