LTE wasn't even an official standard 18 months ago. WiMAX is.
For example, if I had UMTS support on my Nokia N810 past 18 months it would be useful throughout my country, but not elsewhere in the world especially not out of EU. Why? Roaming costs...
We're going in circles. Your statements left the N810WME realm and were globally about WiMAX being vapourware (aka dead end). Yeah, in San Jose, CA, USA, North America, Earth perhaps but the world is bigger than that.
Given popularity of netbooks which come with a 3G (UMTS) dongle it'd be easy to also sell these netbooks with WiMAX dongles.
Because my government, based on EU directive, is currently licensing both LTE and WiMAX for 2 additional telcos besides the 3 major ones I do not see why either one would have won already except current infrastructure.
