I wonder if there is a niche market for something like an old Dell Axim x50v or a Palm Pilot that could do those smartphone functions on a wifi connection, that way you have the best of both worlds, carry a dumbphone. However, you could still walk into a local Library or even some McDonald’s and connect if need be on the other device.

Of course, then you have to inconveniently carry two devices and the temptation would probably still be there.
