Palm CEO Ed Colligan today announced the company will soon unveil a Linux-based operating system for its smartphones. The Treo maker will use Linux to create a platform that has more power for today’s needs like simultaneous voice and data use, but still retains some elements of the Palm OS. Palm hopes this will ease users’ and developers’ move to the new platform. Although Access, the company that bought the Palm OS two years ago, announced it would launch a Palm-compatible Linux platform, Palm’s effort is completely independent. Palm will still produce Windows Mobile powered smartphones as well.
