Some things to think about:
- Xbox MUST be connected to the internet to play a new game.
- Xbox must connect to the internet at least ONCE EVERY 24 HOURS.
- No more letting your friends borrow your games, they will have to pay a license fee (full MSRP of the game)
- Must pay a license fee (full MSRP of the game) to play a used game.
If you are in a situation where you won't have internet access (in the army or something), there's pretty much no point in buying the new Xbox as it will simply be a paper weight.
