I'm sure I'm not the only one who had problems parseing "PS2 branded USB ball mouse/keyboard". But then, people have been making IBM/PS2 jokes since Sony came up with the recycled name so it shouldn't have seemed so foreign...
Other than that, it sounds like fun to have it running linux. Does it come with a full compiler to let you complie any applications you might want? How about utilizing the specialized PS2 graphics hardware? I'm imagining a day when all game development is done for linux because it run on both major consoles. I suspect that's a dream I won't see fullfilled, but it's a nice thought.
