I think the keys are that the friction is so much less than on comparable trackpads and the precision is much higher.

I'm currently switching from OSX to Windows but a hard requirement was the ability to use my MagicTrackpad on Win10 with tap to click and 3 finger drag (both help tremendously with my RSI).

There's a pretty awesome little piece of software called "Magic Trackpad Utilities" that enables that - https://magicutilities.net/magic-trackpad/features
