ATL - SEA the other day, the pilot gave a pre-departure welcome speech, which included a mention of power ports becoming available, with a mention that caught my ears of " ... you'll be able to watch streaming movies ..." as though the internet itself were somehow included (if you weren't a tech-savvy person). I made sure my Kindle Fire was fully charged before takeoff, used it a lot (including watching a movie and listening to some audio), and it was barely down to 80% at landing.
