I'm in a market that's supposed to have full WiMax coverage and it was still never really there. I skipped the Evo 3D so I don't know how it was, but 4G really just meant sudden death for my old school Evo's battery, I couldn't enjoy the speed long enough even when I did get a signal.
So, I will be fine with the 3G and Wifi I have been used to using all this time, and a brand new amazing phone, until they get LTE going, which will really be the test if they can do it right this time. If it fails to materialize again, that will probably be the dealbreaker, but I have hope.
Maybe I'm just old, but I've never been in a situation where it was life or death to be able to download a funny cat video at lightning speed. Yes if it is possible I would LOVE to have blazing fast data, and I know when I do have it I will become massively impatient with everything, but right now it's just for e-peen waving.
