You don't have to know what Hz is to see that scrolling on some devices is smooth and on other (coug..Apple) devices is choppy. 60Hz feels like a decade old phone.
20 years ago I was gaming at 30fps and called it smooth. Now 120Hz feels like bare minimum.
Outdated comparison now that Liquid Glass is lagging my phone.
It will be buttery smooth between the chops.
Actually surprised to learn Apple did the OLED swap and didn't use the opportunity to bump it up at least to 90 hz like the OLED Steam Deck.
