Like the idea of driving down 4G chip costs. I also wonder, why in the world adding 4G adds ~150$ to device cost. But not sure, about the prospects of a 4G chip without 3G/2G . Most often, your network coverage for 4G is limited. Premium vendors like Apple samsung is unlikely to opt for such a device. If you dont move around much, and lives a area with good 4G coverage. Then it might make sense to get a 20$ 4G chip device vs 150$ 4G/3G/3G chip device.
It seems as though all of this is really riding on cellular providers to adopt this. All of today's newer phones provide LTE. What manufacturer would want a phone that doesn't provide Wifi and 3g too?..
I'd love to read a discussion about whether Wi-Fi, 3G or LTE is the most preferred link of choice for IoT and M2M.
I know its horses for courses, but isn't the general hierarchy of preference:
Wi-Fi: Cheap and fairly widely available or easily deploy-able
3G: Nearly as cheap if available
LTE: Least cheap, least available
