tlhIngan writes "The US Air Force, having purchased PS3s for supercomputing research, is now the latest victim of Sony's removal of the Install Other OS feature. It turns out that while their PS3s don't need the firmware update, it will be impossible to replace PS3s that fail. PS3s with the Other OS feature are no longer produced since the Slim was introduced, so replacements will have to come from the existing stock of used PS3s. However, as most gamers have probably updated their PS3s, that used stock is no longer suitable for the USAF's research. In addition, smaller educational clusters using PS3s will share the same fate — unable to replace machines that die in their clusters." In related news, Sony has been hit with two more lawsuits over this issue.
