Bad news for Cloud Computing boosters. A massive screw-up on the part of the Microsoft subsidiary that runs the Sidekick service has resulted in all data stored on the service's servers being lost. Data stored locally on the Sidekick devices is still intact, and T-Mobile will be figuring out a way to facilitate the upload of that local data onto the servers at some point. It's a hard lesson to learn when we rely on someone else to safeguard our precious data. I'm afraid this will be the nail in the coffin for "Pink," the Microsoft mobile device hardware project reported to be based on Sidekick tech.
