I own nintendo ds browser and is far to replace a pc with it, it's only a browser based on Opera and is very slow to navigate online also doesn't load properly some pages.
You need a hacked card for more memory on DS, the Gameboy Advance is actually superior to the NDS as far as memory goes. It was impossible to make a GBA emulator on the DS systems that removed the slot due to the limitations which is why they made cards like this one.
I would know, I was trying to make my own emulator and I couldn't because of the memory issue, these cards have memory built into them and allow the DS to access it.
On PlayStation 2 and up you can install Linux, Playstation actually uses FreeBSD Fedora on it (as far as I'm aware), I was able to clone a PS3 drive using bit by bit copy to an ISO and open it using programs like 7-zip, although Windows couldn't recognize it as a drive if I cloned it to PC, linux likely might have.

I actually have to agree with the rabbit on this one...consoles are literally PCs with no access to the actual OS running them, there is literally no difference (especially now), except they have cheap parts, are more likely to die, more expensive to fix and upgrade, and you can't access the OS underneath without a jailbreak at a minimal.
This is why most Playstation hacks use elf files, linux/freebsd based format, they are designed to run on the system already.
A console is basically a gaming OS for dummies that don't want to deal with problems just to game, the PS5 era consoles have mostly PC parts, Xbox has always just been a literal computer.
I have nothing against consoles honestly, I just realized you were paying for a watered down gaming PC in a fancy case with a locked disc drive format and an Apple style OS for a ton of money and then being forced to buy the same games when they clearly could have run on any of the newer systems
