As this model spreads, we'll see digital cameras, GPS devices, wristwatches and all kinds of other devices with baked-in mobile broadband. This will advance the digital nomad lifestyle because you'll have less need to go find a Wi-Fi hotspot or even a computer in order to upload, download and communicate from gadgets.

in Travel Management pointed out that in-flight Wi-Fi is "spotty but showing promise." Interestingly, they suggested that airlines might start cutting deals with businesses so that employees would essentially get "free Wi-Fi," but paid for in bulk with volume discounts by the companies.

Airlines are starting to test free, in-flight Wi-Fi. American Airlines announced this month that it is through Aug. 23 (use the promo code AAWiFi76194A1 on the flight, and you don't have to pay). AirTran Airways is also from Aug. 1 to Sept. 1 on shuttle flights between Boston and Washington, D.C.

This looks to me like the airlines are sliding down that slippery slope to simply offering free Wi-Fi in a year or two.

Offering free Wi-Fi will be found by the airlines to be cost-effective in the long run anyway. The reason is that with cell phones, including the iPhone, media players, including the iPod Touch, and a new generation of media tablets lead by the rumored Apple tablet, just about everyone who steps onboard an airplane will be carrying a Wi-Fi capable device. By offering free Wi-Fi, airlines can stop having to install and maintain entertainment services. They can place their own ads on the Wi-Fi network connection but let passengers simply entertain themselves using their own equipment.
