You skipped over the biggest handheld PC maker of all. Valve with Steam Deck.

But once again, all of those are PC’s. They’re not game consoles and thus none of them restrict what you can put on them. You’ll also notice that Steam Deck is the only one that has good gaming capabilities with a price around $500. You know why? They own Steam and even though you aren’t forced to do it. Most PC gamers buy their games through Steam. So Valve didn’t go into the handheld market to make a bunch of money selling hand held systems. They did it to make money on game sales, just like a console maker. That’s why there’s ten fold more Steam Decks that have been sold vs all the other handheld combined. Because all the other ones that give a good gaming experience are hundreds more dollars, because those makers like Nvidia, Asus, and Lenovo actually do have to make their profits off the hardware sale.
