You get to make "backups" or your already scratch resistant game discs.
Emulators so that you can play "backups" of older games that you of course own.
You can use linux which was removed after some guy hacked the PS3 through it.
Cons: ... You have to ban someone else's system if you get banned on PSN and want to return.
