I don't think I am. They had a significant isue with joycon drift. I do think some of it was overreported, in that a big issue with joycons is that they have absolutely garbage-tier connectivity, which can also manifest as the stick being "stuck" as the receiver keeps the last direction held to mask intermittent connectivity. But even with that, the sticks were prone to physical issues, at least in the earlier runs. It's unclear how well newer sticks hold up in comparison.

But that is perhaps the biggest technical issue Nintendo has ever shipped, and their handhelds have been knwon for being insanely rugged since the original Game Boy. The Switch is perhaps the most prone to cosmetic issues, but it's still a remarkably solid little tablet. It breaks under extreme abuse, just like the DS ended up with torn hinges and scratched plastic screens, but it's nowhere near fragile. It's a toy built for kids, so it's built for more physical abuse than your average phone. That's not a defense of Nintendo, it's a very conscious decision they've made as an industrial design approach and a business model. It's not good or bad in itself.
