The Switch is old hardware that was under-powered on release, therefore, I expect that I'm not going to be getting 60FPS.
Basically, it's down to expectations. The Switch is absolutely great at what it does, and I appreciate it for that reason alone. My expectations are greatly different compared to a gaming PC/PS5/etc.
My biggest gripes with Nintendo is the god awful way they handle people using their IP to make YouTube videos, etc.
