No docking station - Don't really need one. Thunderbolt can handle most everything, and then you just have power. In my experience most people I see use a laptop only use power and maybe a wireless mouse receiver and a monitor. I don't see many people plugging 12 things in.
Batteries - Macs get phenomenal battery life, it's not an issue for most people. Much like iPhones there is an argument for swappable batteries but it doesn't seen to have a large effect on sales. People seem happier with the thinness and weight savings, or at least don't mind the tradeoff much.
Spill resistant keyboards - Are most PC laptops outside of the toughbook market? I wouldn't have even thought about this.
Matte screen - That was an issue. I am typing from the last matte screen MBP Apple made, I didn't like the gloss. I've seen the newer machines in person and while they do reflect more light they're much better than they were years ago. The better contrast and color saturation would be worth it to me when I replace my laptop.
Then again, I imagine the average person always liked the glossy screens because they looked better at first (much like the poorly adjusted TVs at BestBuy).
Some Macs still have Ethernet, but WiFi is pretty ubiquitous. When I'm at my desk I'd just plug an adapter into my monitor and it would work (thanks to Thunderbolt). RAM and HD are another design decision Apple has made that people seem to accept.
I do love OS X. You seem almost dismissive of the trackpad, but I LOVE the thing. I'm guessing you're a TrackPoint person, and I get that. But the laptop world seems to have standardized on touchpads and Apple's are phenomenal. For years they were MUCH bigger than PCs and the gestures works great. For years PC laptops (especially budget ones) seemed to have odd 'scroll strips' and I read complaints about them in reviews.
I'll also mention MagSafe. It's saved my laptop numerous times and is extremely easy and fast to connect (or disconnect).
In general Apple's laptops are just well built and feel solid. Some PCs are like that, many aren't due to cost. If I'm going to use a machine every day for 4 years I want to know it's well built and holds up well. That's never been a problem with my Macs, anecdotally I've heard things all over the place for PC brands. Things where Lenovo makes great laptops except for line 'X' which is built poorly, or the 2013 version of thing 'Y'.
There is a lot to be said for a well built laptop with very consistent quality, thin, low weight, and excellent parts. It's easy to try Apple stuff in person thanks to stores and it's easy to narrow down what you want because they don't sell 40 individual models (before customization). There is a very large 'no hassle' factor when it comes to buying, I don't have to worry that I spent 5 hours picking the right machine only to have it show up on my doorstep as something I don't like and have to send back.

Now THIS is a potential problem to me. I don't blame Apple for not selling OS X, but I know that I'm at Apple's behest. If they decide to make computers I don't like for a few years I know I either have to wait it out or switch platforms. With a Windows laptop you decide to leave Lenovo and go to Dell or HP without having to change your whole day-to-day environment.
(I'm ignoring Hackintoshes. I don't want to spend the time to deal with the possible problems.)
