Not exactly, mine is kinda borked because of the browser, it performs like crap, something to do with Nvidia drivers, I think, I'm not bothered with choppy scrolling but choppy video and super laggy overlay and big picture are annoying as hell.
I had the same problem in manjaro plasma kde as I have in mint cinnamon.
It's no the prettiest out there but it's not ugly at all, there's no place for violence since you don't even see any other character outside of emails
What age range? I've seen "house flipper" give great results, I think in general those simulator games that give the dopamine hit of completing tasks are good incentives, especially chill games (nothing time based, let them take their time). I've found something like "a little to the left" is not actually great for that, it requires precision and an eye for pattern recognition that just causes frustration when you think you got it but nothing happens.
They don't know that, if they sell cheap enough it might be worth it for a random office somewhere to order a hundred and use them as work computers with no intention to ever buy a game in them. Also they aren't going to be locked, nothing prevents you from getting one and run games purchased in every market under the sun that isn't steam (and/or pirated games).
I don't think they have any certainty that they'll even make decent money on them. I am hopeful that this will be good for everyone but can't exactly see how at the moment.
