Oh haha, it's outdated then! Small heaters for small tanks is something recently put on the market, in fact, I think just a couple years ago 10w heaters were nonexistent and even the little 7.5w were recently introduced. It's been a long process, but people are slowly catching on and the market is slowly introducing more adequate betta supplies. :D I can remember searching high and low for low watt heaters and never finding anything. I was shocked when I saw a 10w heater advertised/recommend on a Marina Betta Cubus 1g Kit, that was a happy day. XP
I did enjoy the video though. :)
