I am not as sure that PS3 will ever get a meaningfull hack. Sure, it is possible.... but good engineering can make a hack almost impossible to pull off. Take a look at Blackberry for instance. Unlike the iphone, hacking/modding your Blackberry is not a practical feat. There is a reason you cant just pirate any ole BB software and get it to run ( though you can DL plenty of generic midp/java apps that will also work on a BB )

Making a "trusted system" in a computing sense, is very viable, and has been achieved elsewhere. Of course there are never any gaurantees, but I think things look pretty good on the security end for the PS3 and there is a high probability it will remain uncracked for the duration of its market life.

some people rly got too much time on their hands.

Its true that modding the PS3 is no easy feat, and even if the PS3 could ever be hacked sony will quickly come in and resolve the problem for instance new fireware.
