I suspect this is a way of them to justify a slack ADSL rollout. "Sorry we dont have and never will have ADSL in your area, but here is a crappy high latency WiMax solution you can frustrate yourself with."
The internet was invented for 2 things, games and porn. Telling me I can now only get porn cause there is too much latency for gaming is telling me I can only use 50% of my service....That aint goona fly.
