I'm being a bit pedantic here, but I actually think it's VERY reasonably priced in its base configuration (the options, however, are another matter...). Having a board that supports 64GB of RAM and 4x Thunderbolt 3 ports doesn't come cheaply. Nor does unibody aluminum. Nor does supporting three 4K displays concurrently.
That said, the things you're paying for may not be the things you care about. If you don't need even one TB3 port, let alone more, then having four of them is a massive added cost that anyone would—quite rightly—not consider worthwhile. I'd suggest, however—and here's where I'm being pedantic—that it not being
worthwhile to some of us doesn't mean that the high cost is
unreasonable; it just means we may not be the target audience.
Putting four TB3 ports on a machine is making a statement that they want this thing to be taken seriously in a professional environment, and by all accounts, it will be. Quite a few people would love to pair these with eGPUs, professional RAID enclosures, and 4K monitors; stack them in colo data centers or mini server clusters; or otherwise make use of them in ways that they are somewhat uniquely designed to work, at least among consumer-grade PCs. I wouldn't be surprised if we end up buying dozens of them for various uses around our offices.
And for those sorts of uses, it's both reasonable and compelling at that price.
I've actually done comparisons occasionally, and though the Apple Tax was certainly true in the past, it's rare that I've found a (EDIT: non-built-to-order) Mac in the last 10-15 years that is more expensive at launch than the
cheapest comparable PC from one of its competitors (I tried to spec a comparable Deskmini out for less than the Mac mini, but I blew the budget simply adding support for 64GB of RAM, let alone TB3 ports). That said, whereas other manufacturers will let you strip away features you don't care about to reduce the cost, Apple generally doesn't. It's their way or the highway.
Macs are generally a good value for the hardware you're getting. The only question is whether you're getting the hardware you want.
Look at all that love for USB C.
Meanwhile their phones use Lightning still. Rip.
I'm suddenly very glad that I held off on upgrading my phone for another year. Hopefully they'll work on making their product lineup more consistent in the next year.
