Ever heard of the PlayStation®Network Downloader? Let me quote it directly from Sony.
PlayStation®Network Downloader is software used to move content from a PC to a PSP™ system.
This software must be installed on the PC before PlayStation®Store content can be used.
THAT's what I'm talking about, it would be nice if something like that would work FOR PS3 content. Period. Not sure where the hell you got all that other crap from. Also, many games have locked saves, let me name a few... Demon's Souls, Bayonetta, Ninja Gaiden, Mass Effect 2, UFC 2010, Gran Turismo 5, etc.
I could keep going, the fact that more and more games are DOING this is pretty worrisome because if something erratic happens to the PS3, you are screwed.
Even with a proper PS3 format backup, that backup only would work on the PS3 it came out of, so if say something happened to my launch PS3. Then I'm screwed. I know people who lost their 200 hours Demon's Souls saves thanks to this.
Oh, and don't bring your crap up about how they locked it due to "PvP". Next time you want to sound smart, I suggest you read properly what the other person is trying to say. It'll save you sometime.
