Although I never found much utility in Other OS, a Playstation 3 feature that could turn the console into a basic computer running Linux, my heart went out to people who used Other OS before Sony scrapped it.
Sony said it removed Other OS in March to "protect the integrity of the console," possibly because one hacker came too close to exploiting the feature in a way that would allow piracy. But now, OzModChips claims to have the first PS3 modchip on a USB stick. In theory, this allows people to play bootleg and homebrew games and make disc backups. Supposedly, it can also bypass firmware updates that Sony might use to banish the hack.
If Sony's piracy safeguards have indeed fallen, I propose that Sony should bring back Other OS. After all, once the integrity of the console is lost, there's no point in protecting it at the expense of users who did no harm.
