The Fate of Mobile Calling

I've written about the convergence of wireless networking and voice over IP (a.k.a. Internet phone) services briefly, most notably talking about Nokia's first WiFi/cell phone product and their more recent wifi-only device. As wireless broadband and WiFi hotspots and municipal wireless networks become even more ubiquitous, these technologies are poised to radically alter the business models of mobile phone companies. Computerworld recently published a great article on this subject and the potential fate of mobile phone services.
