As always, the mousepad can't yet be beaten. While it sounds trite - and I've long since switched away from my original Macbook Retina, IMO the height of Mac's hardware dominance - I still pine for it compared to everything I've used since.
I haven't used one, but newer machines use Microsoft's "Precision Touchpad" standard which is supposed to close the gap and support fancy gestures. Personally I just use the ThinkPad nipple and as many shortcut keys as I can memorise :)
I'm another one who much prefers the nib in the middle of the keyboard to the touch pad. I use a Thinkpad keyboard on my desktop machine for this reason. No mouse on my desk at all and I'm not constantly moving my arm back and forth to reach for it.
I was right there with you for a long time, but the touchpads on PC flagships have largely caught up. I switch between a Dell XPS 15 and a late-model MBP daily, and while I still give a slight edge to the mac, the Dell works well too and doesn't cause any frustration/pining.
I thought the same thing but I switched from a MacBook running Bootcamp to the new Surface Laptop and I actually prefer the latter. It's absolutely phenomenal. Microsoft is kicking ass lately and WSL lets me do all the Linux stuff I need to do (build scripts, etc.).
