I personally think Linux would be the good basis for a games console which ran steam and gave people access to their steam library in a stylish compact box with mid performance level at a reasonable price. However the issue is of course the hardware manufacturer has to make money so the console price couldn't be subsidised except for streaming/remote processing revenue when playing more power hungry games.
However android is still an option. No one yet as far as I know has produced a super powerful android box that could run all android games at 4k 60fps with maximum graphic detail. Such a console would have access to incredibly cheap games and a performance level perhaps higher than the standard ps4 and xbox one. It could also again stream impressive games that are remotely processed which is a source of revenue.
I must admit if someone came up with a powerful games console that integrated both my steam and android libraries with a proper game controller I'd be interested.
At the end of the day I don't know what the Atari box is but if its something that runs a wide range of games and is good value I'm going to consider it. I don't do brand loyalty personally. I always look at the product and see if its works for me.
