At tomorrow's WWDC Conference, one of the key focuses will be cloud computing and an announcement of Icloud. I expect that Apple will announce a model which allows you to stream all of your music, documents and other media from the cloud to all of your devices, and it will work seamlessly with Apple software. It is interesting how Steve Jobs alluded to this at the 1996 WWDC after returning to Apple. Watch the video from the 16 minute point and you will see how he envisioned a model where he would be able to access his content on several devices from the server. It took a while but it looks like Apple will realize this goal very soon.
