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

I'm using Magic Trackpad 2 right now (I strongly prefer touchpads to mice and needed something quiet). It's just a typical touchpad, but it moves parts of movement handling from the driver into the firmware, so it's a bit harder for the software to screw it up. It feels like a larger version of the Synaptics touchpad in my laptop, but with a haptic feedback engine instead of physical clicking.

Having said that, driver support is notoriously bad for most touchpads out there. My laptop touchpad feels pretty bad with libinput, for instance. With synaptics driver it's very Magic Trackpad like - and it's a Lenovo laptop from 2013. The same touchpad feels practically unusable on Windows.

I’ve long suspected that most people (who use a Mac, at least) who still use mice simply haven’t tried tap to click.

Once I discovered that there was no going back. The sheer amount of unnecessary energy wasted on clicking, not to mention the other great gestures.

I'm just an anecdote but I can't imagine I'm alone in hating 'tap to click'. It's the first thing I disable after a clean OS install.

You are not alone. I find that tap-to-click results in erroneous clicks on a very regular basis.

I'm a touchpad lover and I tend to disable 'tap to click' as well.

Maybe I am an exception but I deactivate tapping on all touchpads (Apple or non-Apple) I use. I find the lack of feedback annoying and if I disable it I can also rest my fingers on the touchpad without causing input.

Question out of ignorance, how do you click on the Magic Trackpad without tap to click? From images it doesn't seem to have any button.

The entire trackpad is a button.

It used to be a physical click, but recently they’ve switched to the same mechanism used for the last generation(s) of iPhones, where the home button wasn’t actually a button, but gave virtual Taptic feedback.

Tap to click was the thing I loved the most when switched to a MacBook (ok, other laptops have it too, but when the entire trackpad is imprecise, tap to click makes things worse). My trackpad broke the “click” and I don’t miss it.

It's very good, but a mouse (e.g the Apple mouse) still has better ergonomics, especially for larger movements and longer use.
