So now people are saying that WiFi, or 802.11a/b/g/n wireless hotspots, is going to die. Why? Because we'll all switch over to using cellular broadband (3.5 or 4G) networks.
Hogwash.
That's like saying we'll all switch to WiFi and that Ethernet will die. And that didn't exactly happen.
Granted, WiFi's explosive growth will probably slow down. But will cellular broadband ever be as cheap as WiFi? Will I be able to have my own cellular hotspot in my home for my own network?
WiFi won't die.
