By the time the switch was around people had been emulating on Android for a long time. They can do better graphics but there hasn’t been a game that made me feel like I needed 4K on handheld. The switch really is another golden age for gaming with the switch being hacked so quickly and having such good homebrew.
Meanwhile the switch had the big bootrom usb stack exploit, but everything apart from the original SoC doesn't have a publicly known easy exploit (there are mod chips, but nothing like the 3DS/PS3/Wii U/Vita/PSP/...). There also wasn't that as much "cool" stuff to do as on older consoles with homebrew due to the hardware simply being an android tablet with controllers (which doesn't make a difference as a console, but makes it more boring homebrew wise). So there is the usual stuff (savegames, different controllers, piracy, themes, overclocking), but nothing unique to the switch.
Besides piracy what do you expect from the switch? The PSP had an ebook reader, movie player and could play mp3s as well as other cool old games very early in it's release. It could play media and play games up to the ps1. Modding a PSP vita today is like maxing out a citron 2cv instead of buying an e scooter. When the PSP came out it was amazing. Now it's yesterday's news. I'm impressed by the hackers that did it but the vita just doesn't impress even with hombrew today for the capabilities.
The PSP had amazing battery life and felt like a better Gameboy advance at the time.
Right now it's only the early Switch units that are hackable.
And a lot of indie games, JRPGs, Visual Novels just fit the handheld form factor better than PC or PS4 even if they weren't exclusive.
(Of course, Nintendo still sells (nearly) the same switch for nearly the same price, but a five your old mobile device would go for a lot less nowadays.)
Also the Steam Deck starts at $399.
Granted, I'm playing Skyrim and Portal 2 on Switch Lite so I can't see them on the TV and compare them at the same size as the PS3 versions of those games, but Skyrim at least seems to suffer much less lag and visual glitching than the PS3 version. I don't have any newer console to compare with so I'm happy!
But a pocketable Micro console would be awesome for those times I don’t want to have a full backpack with me, which the regular Switch requires.
This seems like a pretty subjective judgment. Was the Sega Game Gear not a handheld console?
Unfortunately all of Apple's chips are stuck in Apple devices, where they're still struggling to incentivize developers to do ports as standard. So they're pumping out beautiful graphics to beautiful displays for games with shitty touch screen controls that are riddled with ads and/or are just glorified virtual casinos.
Take something relatively modern but no longer too expensive, say an A15 like the Apple TV has, bump the screen to 1080p, and I bet it would scream. Possibly with better battery life.
Nintendo would never do that. I doubt Apple would either. But it would be a very interesting test.
