> This wireless internet would probably work for us speedwise... but because I live somewhere that offers both Comcast and Verizon FIOS, I'm able to get 100/100 Mbps service for $40/month.

This service isn't made for you then. If you watch the video on the site the customer is clear: rural area residents without a hope or prayer of getting high speed internet. Where neither cable, or fiber, or potentially even DSL is available. There are large swaths or rural America who still can't get real internet access, and there isn't money in it for telecoms to build the infrastructure to serve them. And those telecoms have squandered the funds that were specifically earmarked to give those people service.

You luckily have two options for high speed internet. Many Americans only have one. Some other Americans currently have 0. Wireless internet like this might be their best option, even if it's not your best option.
