Mainly piracy. But it basically lets you use your xbox as a PC.
I was intersted to see that someone's using theirs as a firewall.
The xbox-linux program is crazy, people are soldering 128mb ram
modules to the motherboard to get more juice out of the system.
Pretty much once you have a modchip installed you can back up your
games, play various media off the hdd, making the xbox all out media
center really. It skirts on the border of legality, however if you have legit
copies of everything all you need to do is get a large hdd, mod your xbox
and dump everything on to it. That way you have your media jukebox that
you can setup on a network or tote around with you on holliday or whatever.
Not to mention not ever having to take games out of their cases again.
Oh and don't forget the emulators. Hehe, the PS2 is backwards
compatible with the PS1, while the xbox is backwards compatable with every
system made thus far (at least those that have been emulated).
Its convenient, super fun, interesting to work on, and unearths the incredible
versitility of the console disguised PC that is the xbox.
