Apple's announcement of its upcoming iCloud service has sparked a flurry of excitement in the industry. Some expect the iCloud will help Apple keep customers closer to its bosom -- make them "stickier," in analystspeak. Others think the iCloud will give a boost to cloud computing. The iCloud will automate the backup and storage of data -- music, photos and what-have-you -- and make it easy to set up new iDevices because everything on a user's old iDevice will be in the iCloud, and setting up the new one will simply be a matter of downloading that information.
