Worth noting here that most analysts feel that the reason the original iPod was successful was that it only did one thing in an extremely friendly format.

I think the key question here is whether or not the app-universe grows in size until consumers desire separation of widgets again.

I know from my own experience that I found I maximize productivity by having separate devices responsible for separate things. For instance, when I pick up my blue iPod it's for education -- I keep books and lectures on there. But when I pick up my black iTouch it's for fun -- I keep only tunes there. My phone -- although it has all kinds of neat wizardry in it -- I use solely for talking to other people.

Perhaps both trends are true. Perhaps we end up individually separating our apps into physical devices based on preference instead of tradition. Neat stuff.
