I'm trying to figure out what in the world people are going to use these for. Single-app kiosk? Sure, but that's gotta be a tiny market. TV streaming box? Maybe, but it's not clear to me that it really offers anything I care about that isn't already done by Chromecast/Roku. I dunno. It's kind of a cool idea, but it feels like a solution in search of a problem.
Remember WebTV? It seemed like they were pretty popular at one point, if perhaps not so profitable.
