I think many see this as a slap in the face to the consumer: but which would you rather have: the loss of linux or gamer's on PSN with Mod chipped PS3's because as it stand's now that's what would have happened if Sony kept INSTALL OTHER OS on the PS3, yes it could still happen but no sense making it easier for the Hacker's to do it! example: January 27, 2010It is quite possible someone will package this attack into a modchip since the glitch, while somewhat narrow, does not need to be very precisely timed. With a microcontroller and a little analog circuitry for the pulse, this could be quite reliable. However, it is more likely that a software bug will be found after reverse-engineering the dumped hypervisor and that is what will be deployed for use by the masses. Sony appears to have done a great job with the security of the PS3. It all hangs together well, with no obvious weak points. However, the low level access given to guest OS kernels means that any bug in the hypervisor is likely to be accessible to attacker code due to the broad API it offers. One simple fix would be to read back the state of each mapping after changing it. If the write failed for some reason, the hypervisor would see this and halt. It will be interesting to see how Sony responds with future updates to prevent this kind of attack. http://rdist.root.org/2010/01/27/how-the-ps3-hypervisor-was-hacked/ I would rather have no Linux install than to have Mod Chipped PS3's on PSN

Then Sony shouldn't have put that feature in PS3 since the beginning, as hackers will only have to avoid patching and they'll be able to keep on working on it. BTW, as every console now has a remotely updatable firmware, they cannot be 100% hack-proof, even without OtherOS support.
