Their competitors are xbox and playstation and the cost is way more than each of these. You admit you won't even buy it because I guess you are too technologically inclined. And yet it's not a flop to you. Why?
The fact they've worked on running games on linux for over a decade and still only have a 5% market cap does not bode well for them.
This was supposed to be their great moment, and they ruined it with an expensive box with subpar performance. They should have waited. Now after the hype dies down and it doesn't sell, they'll just have another black eye they have to recover from.
Look, I run linux and have for 30 years. I run games on linux and have steam on linux installed myself. But I'm not trying to fool myself and others that it's some great success story. It isn't.
