My options are up to 3mbps DSL, Cable, and Cellular.
January 1st my cable (internet only) went from $55->$87, I was going to cancel but they knocked me down to $60 (25mbps FYI).
Cellular was the better option over DSL (for someone living alone). for an extra $25 I can get unlimited tethering, throttled after 25 or so GB on Tmobile. I could probably make do only streaming SD and doing serious work from the office (my only use of internet at home is video and reading).
I think over the next 5 - 10 years wireless will be real competition, considering it already is for people living alone (not as good, but hits the value point really well, starting to look good enough). Either that, or someone will come up with a need for a lot more bandwidth, 25mbps pretty much covers the typical home today (a couple of 1080p streams and some spare for other stuff). Sure, I wouldn't mind 1gbps, but it's not really worth much extra to me, my cellular currently gets me 25-50 mbps, faster than Comcast until the throttling, I'd gladly pay a $60 addon to my bill for a device that was throttle free, had an Ethernet port, and and worked on the cellular network. My latency isn't great on cellular though (40-60 ms).
Even so, I think cellular is going to be what starts a real broadband price war, it has low capital outlay (as it's mostly there already for making the phones work), it's improving rapidly as the needs are not (4k only tripling them or so).
Comcast either needs a game changer in need or to not be customer hostile, otherwise tmobile, Verizon Wireless, and AT&T are going to destroy them. They need to start now too, as people will spite switch if they don't do something.
