With Microsoft's outright weird decision to bundle the 360 with a 20GB hard drive (with a mere 12GB free for use!), this Datel product may soon become a common item among the gamer hardcore. I know I'm tempted. It isn't strictly necessary yet, but with TV and movie downloads on the horizon, an easy solution to the storage problem is needed.

There are also relatively straightforward guides to exchanging the 360's HD to a bigger capacity one, but those would all void my warranty.
