Let the hive mind of Engadget get that for you.
"I'm in the market for a new phone and money isn't a limitation. I'm also not partial to any particular US carrier, but here are some of the features I'd like to have: WiFi, GPS, good coverage in lots of places, push Gmail (a must!), physical keyboard (a must!), a touchscreen, decent battery life and a relatively slim body. And please, nothing that has a fruit logo on it. No offense to the fruit fans, though. Thanks!"
Just to clarify, the 255 euro Finnish price is including Finland's 22% sales tax, and consumer electronics tends to be more expensive in Europe anyway for various reasons (the PS3 cost about $800 when it launched in Europe!). If the 5630 does ever make it to America it would probably be about $250 unlocked without a contract (plus taxes), or free on a contract.
I suspect this won't get to America though as the Nokia 5800 is already close to the 5630's price and outclasses this model in most ways, so the 5630 may not get enough sales to justify a global launch.
One other interesting point about the 5630: it has a 600mhz CPU, the highest clock speed on any Nokia device so far. What that actually means in practical terms is unclear though.
