Here are a couple of questions to consider:<p>Does Comcast allow a user to purchase additional bandwidth beyond their 250 GB cap?<p>If so, how much does that cost?<p>It's not just a cap, it's a hard limit. If you want more, you are forced to go with the ISP's own "blessed" option.<p>This is a significant portion of what bothers me with these caps. They are not graduated in a reasonable fashion. Instead, they are a cliff -- either entirely, or through absurdly high "addtional bandwidth" costs, limiting the service that the user can receive.<p>THEN, the ISP comes along and offers the user a sole way around/past this limit: Purchase whatever subset(s) of the additional service exclusively via the ISP's "value-added" content. (You can only have more bits if you buy your movies (well, movie viewings) from us.)<p>THAT, my friends, is a monopoly. Especially when you only have one or two ISP options, and they're all doing it. (Again, to you overseas, this is the case for much of the U.S.)
