And if you've preordered your shiny new Xbox 360 but have a older unit at home, you're going to need a little something to move those profiles, avatars and game licenses over. Should you have an Elite (or if you've upgraded your hard drive) you might find the cable you need between your couch cushions, but on the off-chance your Xbox 360 Hard Drive Data Migration Transfer Kit hit the dumpster long ago, you're not entirely out of luck. The one-way, single-use device will retail soon for $20, a mere $5 more than what it costs at the Microsoft Store -- or $19 more than used cables fetch on eBay.
