The day i can fit the power of a computer capable of emulating the switch 1 in a gameboy shell will be glorious.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

We must be pretty close on that by now, I can emulate a number of Switch 1 games surprisingly OK (not amazing, just OK) on my S21!

The only caveat here is the fire-hazard non-removable lithium batteries.
This is, in my mind, one of the benefits of laptops over micro computers: integrated UPS. Even an old, degraded battery will probably get you a couple of hours with the screen off.
IME, power consumption is going to be worse overall, for any laptop likely to be in the recycle bin, it's probably double the consumption of an ARM SBC. The integrated UPS and usually decent power conditioning of the power supply saves you more money with a laptop. Plus, keyboard and screen for emergencies - I just generally expect that, over there life of a micro I'm going to have to drag out and plug in a spare keyboard, mouse, and monitor because something in a device, or an upgrade, or BIOS flash, is preventing a boot.
There are a lot of good reasons to use laptops instead of SBCs, if you don't mind the extra power draw and (as she says) don't have size requirements.

Replacement is usually removing 6-10 screws and prying the case with a guitar pick or old credit card. There is most likely a disassembly video on youtube. Batteries from aliexpress or the like are usually cheap (although probably more expensive than the computer). Depending on the application, the "built-in UPS" can be nice.

Or get a used thin client (e. g. HP T620, T630, T640 or Dell Wyse 5070). Cost: ~40-100$. Biggest advantage: Passive cooling, i. e. they're absolutely quiet.

The power constraints are more important to most than the size constraints honestly.

You lose the I/O and power efficiency is no comparison. You can get better power efficiency and sometimes some I/O with an old router and OpenWRT, but you'll be in the class of a Beagle Bone and a much harder learning curve. I've never managed to get a sensor or peripheral working on some old laptop's SPI or I2C buses like how easy it is on a Rπ.

It's low power that is still making arm small computers popular. It's impossible to get a pc down into the 2-5 Watt power consumption range and over time it's the electrical costs that add up. I would suggest the RPI5 is the thing to get because it's expensive for what it is and more performance is available from other options supported by armbian.

Low power and arm architecture are big differentiators between Pi and laptops.
I totally agree recycle laptops where possible, but they're generally noisier and less energy efficient plus the battery degrades over time and is a fire risk.
They're not necessairly a good fit for always-on server or service type uses comparef to a small board like Raspberry Pi. But a cheap or free second hand laptop is definitely good for tweaking, testing and trying our projects.
How many people keep up with this misconception RPis are ultra efficient? They are bargain basement SoCs. The power draw isn't that low (25W PSU), and the performance they deliver isn't great. They are all made using older process nodes and techniques that result in less efficient processors. Add those together and you will find they have less performance per watt than all modern laptops with the screen turned off, and less than most Mini PCs. Mini PCs and other SBCs are where it's at for efficient home labs. If you can find a Mac with Apple Silicon for cheap they are even better. Everyone in the home labbing community pretty much knows this by now. I struggle to understand why Lemmy hasn't got this through their brains. I think it's partially the miconception that ARM is always better, and partially down to people not understanding that low maximum power draw and efficiency are the same thing. Not even thinking about idle power or performance per watt.
raspberries were viable while those were cheap. I think I got a 3b (plus?) in pre-deficit years for like $25 second-hand AND I got some shitty case AND a microSD card AND it could run off of a somewhat normal USB phone charger. so using those instead of a 10 year old decommissioned desktop was an awesome value proposition.
nowadays, those devices are encroaching on trip-digits territory and the power adapter is like $30. the computing power you can buy for a third of that designates raspberries exclusively for niche use cases where footprint and power consumption are primary considerations.
not to mention fake Jason Statham just rubs me the wrong way, like all them "visionaries". he makes this sound like he's the head of Feed Africa or something, on a noble mission to save humanity and whatnot.
