All of these are correct but have nothing / little to do with the quality of the main trackpad use experience, which was still great on Macs before it got haptic pushes, larger size, glass, etc.
The 2005 Powerbook was the first to support multi-finger input on the trackpad... probably not a coincidence. We now know that the tablet/phone project kicked into high gear around this time as well.
I think this is really where Apple took a big step in their trackpads across the board. I had an iBook from before this time and while the trackpad was nice, I did not think it was way better than my PC laptop's trackpad. The biggest difference was that the Mac trackpad was about 30% larger.
Apple also invested in touch concept company-wide, including gestures in their marketing and shipping a trackpad as a first-class option for desktops in 2010. I think part of the reason Apple has done well with touch is that they just prioritized it and tried harder at it.
As the above commenter mentioned: a combination of hardware & software gives Apple and inherent advantage, which—along with Apple just having a culture of prioritising UX in their products (and MS kind of being in decline at the time, before their recent resurgence)—would explain the pre-iPhone trackpads being ahead of their competitors.
With Surface, while MS do control both elements, they're playing catchup on years and years of progress by Apple.
Combine all that with the recent mainlining of iPhone R&D and catching them seems really really tough.
Hell, I even have a low power, super cheap Lenovo laptop (Atom CPU, IIRC), and I much prefer the touchpad on that over my MBP's!
Honestly, it feels like some Apple users almost fetishise over their MB touchpads! I truly don't get it.
Scrolling, zoom, clicking, what else do I need? :/
2- The trackpads are flush with the body of the machine. I've often used PC trackpads where you were expected to scroll using the right side of the trackpad, but it was basically unusable because the plastic bezel was in the way.
3- The finger tracking is phenomenal. I don't know, it "just works", whereas PC trackpads would often lose track of my finger, forcing me to repeat the movement while pressing harder.
4- The multi-touch is great. 2-finger scrolling feels way more natural than using the side of the trackpad. No wonder it's been (often poorly) copied by basically everyone else.
I don't doubt that some PCs have very good trackpads, but Apple's has been consistently a pleasure to use on every Mac I've used, to the point that I don't bother carrying my mouse when I travel with my laptop.
And this includes Microsoft hardware such as Surface Books. (To be clear, it’s a hardware issue, but one would think Microsoft would shell out for better trackpads on their flagship devices.)
On my MBP, it really feels like I have to press with far too much force to get it to "click" (which isn't great given I suffer from nerve damage, but I felt the same about the trackpad even before that). By comparison, I just make a "purposeful", light tap on any other trackpad.
Also, you can just use the bottom part of the trackpad exactly like you'd use a button, it ignores touches if you just rest your thumb on it. Works really well.
Truely loathsome machine!
The keyboard is utter garbage too - it would be comically bad if the dn thing hadn't cost so much :/
My laptop has a Synaptics trackpad and while it doesn't have stuff like force touch, it's just as comfortable as using a mouse in many occasions.
I haven't used a mouse regularly in like 7 years because I prefer the Apple trackpads to any mouse I use. (The one exception is video games)
