I don't consider internet via coaxial cable with 300mbps download and 5mbps upload to be broadband. It's probably split between too many houses, and they boost your bandwidth to 300mbps for a minute or two to make it seem like it's fast, but they won't sustain it.

I also don't trust the economic incentives of a company that makes more money selling media than it does proper broadband service.

Dealing with fiber to the home providers is much nicer, with symmetric 1Gbps down and up connections. You can feel the connection is much snappier, have multiple FacetimeHD and HD video streams going, and you don't even notice. And I can stream from my devices at home when I'm away because there is actually available upload bandwidth.
