I'm talking about world-wide.

Say 3-4 years from now, the footprint of LTE vs. WiMax.

Because it has implications for devices like Mifis and so on, the availability and price of devices and services.

Especially on a forum like this one where some people visiting the US are interested in the same prepaid data options which are common in other countries. If the US wasn't one of these CDMA ghettoes, maybe there would be such options already.
