Anyone else heard of this? Basically, they allow you to copy games onto the PS2 hard drive (or add one of your own!), and play them directly from the hard drive (a la a modded Xbox).
I'm a sucker, and ordered one, despite the fact I only own about 6 PS2 games, but love hack-ish technology like this
