Right now content is divided into three silos, TV Listings, On Demand and (in the prototype version we saw) Play Now, with the first a touchscreen TV guide, the second Comcast's traditional video-on-demand and pay-per-view offerings, and the last streaming video content from the likes of Starz, Showtime and HBO. You'll only be able to watch streaming shows from the premium channels you already pay for, of course. Avatar looked pretty good, albeit letterboxed on the iPad's 4:3 screen, and over a good WiFi connection the app was able to jump from spot to spot in the film with no perceptible delay.
Comcast reps told us the company's getting so many suggestions for ways to improve the app that it's going to try to issue new updates every month, with streaming video the first out of the gate, followed by (in no particular order) the ability to manage and delete DVR recordings, suggest new programming using push notifications, and emulate the regular set of buttons on a standard Comcast remote. If that sounds like yet another reason to make the iPad the center of your home, however, don't run out to the Apple Store quite yet -- Comcast's hastily working on versions for BlackBerry, Android, and even your web browser too, in the quest to make all our personal computers bow to the power of cable. We're finding it hard to complain.
