Why did the phone companies cling to expensive switched network standards even as packet-switched voice grew robust enough to deliver acceptable fidelity at a much lower cost per connection?
Sprint TV's also included, of course, but it just hangs on 4G whenever you try to watch a program -- we had to turn it off and use EV-DO to make it work, which is pretty counterproductive considering how much better it could look on a faster, lower-latency connection.
