Be careful there - the bulk of computing is always in the background - the consumption of the results of that computing may move towards phones.

Take banking as an example, pulling up your bank balance, or making an online payment, is nowhere near the computing power of actually balancing the transactions at all banks across the world each night. You get a tiny sliver of a tiny report of the computing that happens in the background.

Entertainment, personal tools, communication - those are moving mobile. But that is just the surface.
