I'm a Comcast TV and internet subscriber (not really by choice, as in many places it's the only solid option). Over the past few weeks I've seen an ad from, by, and for Comcast promoting this service... over and over and over. It shows a kid in school with some narration about how everything would be better if only he had access to the internet, then he goes home, and imagine that! A Comcast truck is sitting outside his home, hooking up some internet service!
Comcast loves kids, loves schools, and wants to help all students do research for their education! Yeah, right. This is a very low cost (or free), but also extremely low service plan. You have to be around or below the poverty level to qualify. The local news did a segment recently and the way they presented it, Comcast won't be letting you sign up unless you can prove that you qualify for food stamps and free school lunches. I'm not looking to go into a welfare debate, but living in a city with a fairly high number of section 8 residents, many of the folks who would qualify for the Internet Essentials plan are already paying Comcast for much better services using subsidies from other sources.
I love the idea of internet access being available to everyone, but don't think for a moment that Comcast is doing this out of some kind of corporate benevolence. It was required the last time they were involved in a giant merger (buying out NBC) and they're finally getting around to promoting it in hopes of their next giant merger (with Time Warner) being approved.
