"PS3 was neither powerful nor low power so the game box was rarely used as a NAS - cheaper maschines for that around"
PS3 *is* powerful thanks to the CellBE processor, and people actually using the OtherOS feature, like me, were actually monkeying around with the special features of said processor. Of course, most of those who dabbled with Linux on the PS3 were trying to run it as a regular NAS/Desktop box, which sucks given the low RAM specs on the box. But removing features like that is pretty much frowned upon. My original phat PS3 is still on 3.15 FW, I ended up buying another PS3 to play more recent games and have PSN access.
The irony is that Sony's boneheaded decision didn't hit the "nonmarket" ... it hit the crossover market of dudes like me who actually play games *and* tinker around with Linux. That made it a FAIL, which morphed into an EPIC FAIL as it energized enough crypto-geeks to crack the box.
