As someone who has spent a lot of time in IT working with regular old Joes that just want their computer to connect to the internet, I say no. Most regular people have to idea what the hell WiMAX is (was) and offering the whole WiMAX situation as an excuse to them is pointless. Most regular people just want things to work and they honestly couldn't care less how or why they work. On top of that, NGN was going to be the one thing that really improved sprints network before the end of the 18-24 months. As far as I know, the WiMAX hold up didn't affect NGN's timeline at all. NGN was about densifying and installing new small cells. Whether sprint has 40mhz of free spectrum or 60mhz of free spectrum doesn't affect their ability to install small cells. Yes, maybe lack of spectrum affects their ability to use them but that's all resolved now isn't it? And we're still pretty far away from the final date...
