On your point on #1, Actually that goes as far as the Fifth Generation Of Home Video Game Consoles like Sega Saturn and Sony PlayStation. (I'm talking about Disc Based Home Video Game Consoles.)
On your point on #2, The Storage Format of Nintendo DS, Nintendo 3DS, Nintendo Switch and Nintendo Switch 2 are not Cartridges.... These are Game Cards that's basically Flash Storage like SD Cards. But I get your point there.... (Gonna be talking about actual Cartridges specifically for Nintendo 64.) But there are Pros and Cons.
Pros, these are quite durable and since the Game Data would've been loaded from the Cartridge all the way to the Console once plugged in, instantly there are no Loading Times.
Cons, these are quite expensive to produce compared to Game Discs and has very limited Storage Capacity compared to Compact Discs at the time during the Fifth Generation Of Home Video Game Consoles are one of the Major reasons why Nintendo with the Nintendo 64 were simply behind Sony with the Sony PlayStation.
And even on their Home Country in Japan they deliberately flopped in the Third Place where Sega Saturn simply enjoyed a simple success.
That's because many developers jumped ship to Sony PlayStation because of how less expensive it was to produce games for and how much Storage Capacity Compact Discs had compared to Cartridges.
On your point in #3, Yeah, you're right, but Game Discs were fine as long as you properly take care of these.
That's more on the owner on how the owner takes care of the Game Discs.
On your point #4, Yeah.... I agree with you on that though I had quite preference on Sony PlayStation Portable for a lot of reasons like Hardware Power and It's Physical Format and how much nicer the games were there and how it's much more than a Video Game Console like you can do other stuff on it like Browse the internet and play music and watch videos, there's quite a good amount of stuff you can do on it.
But I do have some really good appreciation on Nintendo DS and it's also pretty great on it's own way and also had a nicer library of games.
Both are great I'd say.
On your point #5, Exactly.... Many Game Cards barely had the game on it and have you to download the whole game, and Physical Copies only having the Game Key on it. LOL XD
On your point #6, Hm.... Okay but I don't think many craps on Nintendo 64 and many had huge appreciation on Retro Video Game Consoles nowadays and Modern Gaming Console Industry is quite getting a lot of bitterness from the Gamers.
So yeah, I don't see any problems on people playing Nintendo 64.
On your point #7, I do agree the best way to play Retro Video Game Consoles is on a CRT Television Unit.
