So Sam Nazarko is coming out with his own platform. I have been using his crystalbuntu on my apple tv for years now and have been satisfied with his support. He is calling it the Vero and it will cost $199. What makes this different then most streamers is it will be designed to work out of the box. No SSH or rooting needed. He also says he will support the thing for 3 years worth of updates, maybe more.
The specs are a little meh, but you are paying for the working right out of the box feature. If it was $100 I would say it is a must buy. For now, you should keep an eye on it because his code is so good.
