I am wondering, if you buy this sized memory card, will you be able to transfer game add-ons and such between 2 different 360 consoles with different accounts?
You can transfer saves and profiles, but that's it; the downloads are encoded to your account and your console and can't be transfered. You can recover your account on a second system and transfer the downloads to that system (and go back and forth), but you can' exchange them just by using a memory card.
