I owned a Switch 1, and it certainly was the Nintendo console I touched up the most. I replaced the back panel once before I got a Lite and then an OLED.
I will say given how much I took that thing on the road and the beatings it took I never found the issues unreasonable and I only ever had to fix cosmetic damage (joycons aside). I've seen Switches get a TON of usage, too.
It's not Nintendo's most rugged console, but it's certainly not a "fragile little thing" as I would define it.
Let me put it this way, I'd much rather fix a broken Steam Deck, but I was way less worried about breaking a Switch.
