I'm really interested in the possibilities presented by the addition of the "upload" soft button to the iPhone and the increase in storage on .mac. I wonder if we might see future integration between computer, device and online service like this to use your .mac to host media content that can be checked in or out on your iPhone/iPod via wi-fi. It's a thought and maybe not even remotely likely but that would be on hell of a good example of convergence.
