I have AT&T Fiber - $70 a month all in no extra fees are taxes. Gigabit up and down theoretically. I can get 600Mbps/600Mbps on a bad day wired and 900 u/d on a good day. It's unlimited.
I'm not saying that wireless is a good alternative for everyone but I know a lot of people that could get away with the "unlimited" plans that carriers offer. In the future it could provide real competition.
The plans aren't throttled any more - as soon as you reach limit they automatically cut you down to 2G speeds, you are "deprioritize". Meaning that if you are in a heavily congested area, your speed will be lowered to give lighter users full access.
When we were between renting and buying we were in a place with horrible internet and we used our phones on t-mobile for everything - including streaming to an Apple TV. We used 70-150Gb per month mostly at night with no noticeable speed issues.
For technical reasons, I'm more accepting of wireless data limits than wireline. No matter how much a wireless carrier spends, they can't beat physics. There is a limit of how much data can be delivered over a certain spectrum (Shannon-Hartley theorem?)
