Think you're good at turning down the upsell? Try saying no to adding WiMAX to your home internet service for the low, low price of whatever Comcast wants to charge. Thanks to a multi-billion dollar tie-up with Clearwire, Comcast has been offering WiMAX-based internet services in a few markets, but now that On Demand Online is a go, it makes sense to think that the operator would use that as leverage to get people hooked. For those unaware, ODO enables Comcast pay-TV subscribers to watch a vast array of programming from any internet connection, which of course means that any ole 3G / 4G data connection would work just as well as Comcast's own. Oh, and while mobile TV is pretty good -- and we're going to let Comcast finish -- watching HDTV at home with a DVR is definitely the best scenario of all time.

Update: Just to be clear, this service won't deliver TV straight to phones.
