Yes, but is that worth the price difference for people?

To me LTE is not that hot, at this moment in time.
Deployment in my region is still sketchy, and the high speed is not really that interesting, given that I am still limited to 4GB/month of usage.

This will hopefully change in time, but let us say that in two years the LTE deployment is complete, and data rates are lowered according to the new availability (which is dubious, as operators will delay that as long as they can):

I will probably buy a new phone at that time, so, "future proofing" it by buying a more advanced model was not really worth it.

Bottom line: it makes sense to pay a premium for new technology only if you are going to use immediately, not in the hope it will be useful in the future, because you may not be using the same gadget when you finally could use that technology.
