When it comes to Microsoft and Sidekick, I no longer have any doubt about it. There wasn't any cloud here; there wasn't even competent DBMS management.
If I were a Sidekick user, and I was lucky enough to get my data back, I'd be moving it to another smartphone system as fast as possible. Even if Microsoft can make good on their promises, they've shown that their fundamental data management is flawed. I'll trust my information to a better-run system thank you very much.
