It will be a long time before a phone will be able to carry out computations more efficiently than the computer in the next room.

You stated an argument that is a truism as if to make it relevant. In my view, the computer on the phone/other handheld will never be able to carry out computations more efficiently than the (bigger) computer in the next room because there will always be some (diminishing) computational efficienty from size. But a more relevant question is at what point can a cellphone/handheld do things good enough to threaten the PC (in much the same way as the PC threatened mainframe growth without really cutting into the core market that mainframe had).

Eventually, I will be able to from my handheld use the computing power of other handhelds and other computers. At that point, indeed the handheld becomes something of a dumb terminal that aggregates everyone else's computing power (particularly idle bandwith), whether in small or large computers, across as distibuted network. [Until human sleep becomes unnecessary, 1/3 of the world's computers are going to be not very heavily used directly at any given point in time.]

Given that you can get a palm or other handheld with as much power as the computer in 1993-94 (if not later) and given that the cost of linking those computers together is falling and falling, I think the threat is must closer than you apparently do.
