Portable Phones

From Freakonomics:

David Pogue of the New York Times points out that, in the midst of last week’s iPhone mania, most of us missed T-Mobile’s announcement of an innovative new system in which, under a certain plan, all calls made within range of a Wi-Fi wireless network are free.

The new T-Mobile cellular/VoIP WiFi crossover is the real smart-phone feature consumers should be demanding. The iPhone could have this capacity through a software upgrade, and only in implementing this feature along with opening up to other carriers, greater plan flexibility, and faster data networks would their elegantly designed product be truly compelling. Until then, I am holding out.
