Speaking as someone the rest of you might consider a Luddite because I have a feature phone (it's a Samsung with a touchscreen, I don't know the model), the devil's in the details of what the carriers require of you to connect the phone to their network.
Verizon requires you to have a data plan to even use (e.g.) an iPhone. Even if you never use the data service. If Verizon considers your phone a "Smart Phone", they require you to have and pay for a data plan to use it. My understanding is that the other carriers have the same policy. The people that are buying these phones are paying these monthly fees.
If you knew me, you'd know I'm not really a Luddite. For example, when I play my guitar, I don't play with a tube amp, but use a device that models a tube amp that is then plugged directly into a P.A. I pay for said device (a Line 6 HD 500) with the money I save by not paying for a data plan. I prefer to say I'm frugal.
Also, what others have noted: It's Gartner. Seriously?
