If You're Going To Kill It, Open Source It
ptorrone writes "MAKE Magazine is proposing big companies like Cisco and Sony consider 'open sourcing' their failed or discontinued products. The list includes Sony's AIBO and QRIO robots, IBM's Deep Blue chess computer, Ricochet Wireless, Potenco's Pull-Cord Generator, Palm, Microsoft's SPOT Watch, CISCO Flip Camera and more. MAKE is also encouraging everyone to post about what products they'd like to see open sourced."

IBM doesn't play chess with the Universe.
