Joysticks: Probably Still Drifty
Joy-Con joysticks use a potentiometer to read the voltage at a wiper that slides across a strip of resistive material. That material wears down over time, or plastic and dust can dirty the sensors.
Stick drift is a huge problem with other Switch models. One survey found that 40% of Switch owners had problems with their Joy-Cons drifting, and things didn’t get any better with the Lite or OLED editions. After a bunch of lawsuits, Nintendo’s president even admitted it and apologized, setting up a free repair program for customers in some parts of the world.
That’s kinda the thing, a lot of people were basically just wanting just another switch because they liked the switch’s formfactor. It may not be innovative, but why innovate just for innovation’s sake, y’know? It’s a better switch, both in some improvements to the formfactor, and in the same way the Ps5 is just a better Playstation than the ps4.
