How does the PS3 remain as the only unhacked system? And for how long?

[Ail]

As long as burning a Blue Ray is more expensive than renting a PS3 game online you won't see widespread hacking on the PS3.

The size of the data you have to move as well as the others issues you have to deal with should prevent any hack to spread to a signigicant number of users.

That and even if it was, Sony can just push another firmware update...
