Actually, I do Netflix, Hulu, and Amazon Prime. I do Prime mostly for the incredibly cheap shipping. These days, I'm mostly out of the hardware biz, but sometimes I still have to sell some PSUs or whatever. I also buy and rent text books from Amazon. Costs about four bucks to upgrade from free 2 day to overnight. With what I save on shipping, my Prime membership pays for itself about every 2 months.
But, both Hulu and Netflix offer better video. Amazon tends to offer a season or two of a show for free, and then they want to charge you out the wazoo for new episodes. I watch a couple of shows on Hulu, and they have a better selection of Anime than Netflix, but Netflix produces better in-house content like House of Cards, and they have a great selection of Brit crime dramas. I'm a serious British crime show junkie.
