I stand by what I said. It may not be slower for you.

Apple's palm rejection is also top tier, though other systems have been getting better. My current Dell seems fine so far, but at my last company the Dell I had was almost unusable due to my cursor just teleporting around my document randomly if my hands got too close to the trackpad (which is where they have to be to type).

Not sure if it's a hardware (Dell) or software (Ubuntu) improvement, but thank god.

GNOME on Wayland has lots of useful gestures out of the box. It's part of the DE though, so lots of DEs don't have them.

Using Gnome (for whatever reason), I'm used to two finger scrolling and three finger swiping just working by default.

"Without issues" is a stretch. You need to use two hands or be skilled with one. Its trivial on a mouse or a pad with a discrete buttons.

But ok, what about just dragging a long distance where you would normally lift the mouse or finger? Is there some hidden gesture for this? Maybe once your initial drag finger hits the edge you need to use two more to do a move gesture? But I've seen that trigger scroll and/or pinch-to-zoom.

I have the external apple trackpad (the most recent usb-c version at that) and this click-to-drag and then attempting to scroll does not work on Linux. Seems like this might have been a particular attention to detail on part of macOS devs.

As far as I know touchpad implementations just report finger locations and its up to software to interpret what a combination of these gestures means.

How does that work? You've got to tap the touchpad to trigger the initial click, don't you? For some reason, I really HATE tapping a touchpad (let that be an Apple or otherwise), it breaks my flow, I suppose? (like, you have to pause at the cursor's location, lift, tap twice to initiate a dragging event, then finally move on) whereas on the ThinkPad I daily drive I do all the cursor movement/scrolling with my right hand and the selection/clicking with my left thumb on the physical key that sits on the top of the touchpad sensitive area. That makes click&drag workflows super efficient, I find.
