I'm moving to another country. Should I take my Xbox 360 or buy a new one there?

Question

I'm about to move to UK from Poland and would like to know if it's better to buy a new one over there or take mine with me.

Main aspects:

• UK have different power sockets, but adapters are available
• Voltage is 230V in both countries
• What about my Xbox Live account? It's registered for Poland.
• Is there anything more to it?
