So can quite a few Mac models on the Apple website. Pretty sure that “the competition” has a model or two in its product line up that is not as powerful or capable as another model it sells.
As for all of those other things you said…I have tiling shortcuts on my Mac via a lovely little program called rectangle that does so much more than Windows ever could. I have literally never ever wanted or needed a clipboard history but there are plenty in the App Store if I did. My Mac doesn’t open up my music player when I connect my earbuds (took about 15 seconds to disable that in settings)…and fun fact, my earbuds move between my iPad, Mac, and iPhone pretty much seamlessly which is really nice. I do carry a decent USB-c hub that weighs about 2 oz, so your right about that…but the power adapter that I use that can charge my Mac, iPad, iPhone, Apple Watch, and earbud case weighs about a tenth of what my wife’s Windows laptop power brick weighs and fits in my pants pocket, so I don’t mind that extra 2oz in my bag.
But hey, you buy the machine you want for the reason you want.
