I don’t think it’s a US American thing per se. Refried beans are a common staple of Mexican dishes and may incorporate lard (as will more authentic flour tortillas). They’re mashed, not whole beans.
And while I wouldn’t use them in tacos, canned baked beans like those you’d find in the UK may also not be vegetarian.
The Deck might be a good fit.
I say this as someone who doesn’t own a Steam Deck, but do understand their utility. I do own a gaming laptop, however, and believe the pros are balanced by the cons. Depending on what factors matter more will impact your choice.
Steam Decks aren’t going to be able to play the latest and greatest games in good quality, but then neither will most gaming laptops. The laptop may still perform better than the Deck, but it doesn’t quite have that “play literally wherever” utility that the Deck does.
The thing I often joked about with my gaming laptop is that it’s not really a laptop, it’s a desktop with a laptop form factor. But I do mean that seriously—if I tried to play games with it on my lap, I would literally burn my legs. And because it runs so hot, I have to keep it on a separate cooling pad to help regulate its temperature over longer play sessions. It also can’t go more than an hour on battery without dying. All that means that it’s honestly a pain to move, because I need to bring the laptop plus cooling pad and power cables for both.
And all that being said, gaming laptops today are really cheapening out on build quality. I had to RMA my first laptop from MSI because it melted the thin membrane below the keyboard and keys started sticking. All the manufacturers are cutting corners these days, so it’s hard to find a gaming laptop where the expectation is that it still works after 5 years.
If the kid still needs a computer for schoolwork and such, a gaming laptop would be the easy choice, and just make sure he’s handling it with care when taking it to friends’ houses. But if you’re looking for longevity, I might recommend avoiding some of the “gamer” brands and look more at “professional” laptops that have decent hardware and are built a bit more durably, albeit at a premium price point. But if it’s just a dedicated portable gaming machine he needs, I’d opt for Steam Deck or similar.
