Despite its uncertain fate, Sun soldiers on. Monday it trotted out a cloud-based multiplatform desktop as a service for K-12 and community colleges that can run Windows, the Mac OS, Linux and Solaris applications to nearly any client device, including its own Sun Ray thin clients. Sun claims it's the industry's first full-function, cloud-based desktop as a service. It runs on Sun's Open Cloud Platform. Its subscription pricing can run as little as $1 a day per concurrent user. Ashbourne Technology Group is apparently taking it to market.
