the fine print, Xfinity TV's latest update for the iPad allows you to "play movies and TV shows anywhere and anytime on your iPad using a Wi-Fi Internet connection." The deal is for select networks (aka not everyone's on board to start) including HBO, Starz, Showtime, and Cinemax. Version 1.1.1 is now available; we're downloading now and will let ya know exactly what we find.
Update: We've taken it for a brief spin, and it looks like only ten networks are currently available, but there's still a hefty selection of content to choose from: BBC America, Cartoon Network, Cinemax, Starz Encore, HBO, MoviePlex, Showtime, Starz, TBS, and TNT. All are VOD only at the moment, but we hope that live streaming could theoretically be around the corner. Video starts streaming pretty quickly, and while quality probably won't be as good as your 1080p TV, it more than suffices for the iPad's 10-inch screen -- especially the HD stuff.
