Earlier quoted context omitted.
I guess I should have clarified. My only devices are a Pixelbook and my work MBP - no desktop. Playing at home (or work) are totally fine for me. Playing games like Hearthstone (where latency isn't breaking factor) is fine with me as well.
FWIW Hearthstone calibre games are already playable on any moderately recent smartphone. Not much gain from Stadia in that regard.
There are all sorts of seemingly low-resource-intensive, low-latency, even old games of that "calibre" that stutter on my Macbook Pro.
