My flight today LAS-MDW (an 800) had the Free TV from Dish offer. It included the live streaming TV and the video on demand shows, and it worked somewhat well (freezing a couple times, requiring a reboot on my laptop.) They make you watch a Dish ad, but only one. There's also a link to a new subscriber offer (as mention at the link referenced above) and a separate offer for 500 RR points just for giving them your contact info (after which you'll probably receive marketing).
