You can stay where you are if you want linux. Just use a 3.50 spoof and it will help you boot some games. Now if you update to 3.41 you can play but a.few of the.newest are cracked here and there but will not ever run on 3.15. So you need to ask yourself is it worth not playing all those games to keep linux is the.question you should ask. If you are a linux fanboy then by all means sit right there as they are gaining more and into the innder workings of the ps3 this way.
