You have to wonder if WiFi as a broad area service is last years news. 3G networks like the Verison and Sprint EVDO service is very widely available today, delivers a very respectable and predictable 500-700kb service with peaks above 1mb (theoretical 2.4mb today) and the cost has to continue dropping as the user base increases and competition prevails. In other regions UMTS will do the same. We are already seeing devices (smartphones, laptops, pda's) with EVDO radios built in. I can imagine by the time a regional wifi service was built out that EVDO or its next iteration will be available, all you can eat $19.99 a month just like the 2G and 2.5G networks are today.
