For me the touchpad experience is not just about the hardware. I got a Magic Trackpad for my Linux desktop hoping that it would at least be somewhat comparable to my MacBook. But scrolling and gestures are nowhere near as consistent and fluid as in macOS since the software support just isn't there.
As a fairly typical example, getting Firefox on Linux to actually scroll smoothly takes googling and fiddling with settings. Gesture support is hit or miss. On macOS, Firefox behaves just like any other native app in this regard.
This was a few weeks ago. IIRC, the issue with Firefox was not that it didn't scroll but that the scrolling wasn't inertial unless you changed some settings.
