@freakqnc: the boot file looks like it is a real binary file. The readable texts are just some text resources. So nothing interesting there.
The mac mini is a very god choice compared to the atv. It's a real computer (with all the dis-/advantages) and only costs €600. With frontrow it can also act as a decent video player.
For people who want to run a real mac os and don't want to tinker around, the mini obviously is the better choice. Trying to intall leopard on a ATV is some sort of hobby, knowing that this will never be a feasible thing. But nevertheless is is fun ;-)
