The mainstream services, like amazon, hulu, HBO, and netflix, have very rich modern apps at least on the latest gen rokus. The older rokus probably lack the horsepower to use the newer apps.
Makes me wonder: if the Roku was released today, how successful would it be? Seems like they have a huge first mover advantage in that people know it. But now there are lots of big players in the game who can really polish their respective products. I guess this IPO is supposed to help with that, but I feel this just means that there's a challenging road ahead.
