Other than the Mac Pro and mini, there is NOTHING "Outdated" about the Macs.
Overpriced? Prove it, spec-for-spec. First, you have to find another Laptop with 80 Gb/sec I/O bandwidth, and that can drive TWO external 5k Displays PLUS the internal display...
I'll wait.
You're right as I have gone to configure laptops with the same specs as the latest MB Pro that I would want. Namely 16 gigs of RAM and a 1TB SSD, plus the current i7 processor. They are within $200, if that.....but the Windows laptop will have a superior GPU. My issue with the 2018 MB Pro and the two previous year models are the ports. All USB-C/Thunderbolt. Need to hook up to an external monitor? Adapter. Use a common flash drive found at any store or office? Chances are super high that it's USB-A. You'll need an adapter. Ethernet port...adapter (although to be fair they haven't included ethernet ports for awhile now). A video/photo guy with SD cards? Adapter. Yeah they have USB-C hubs, but their obsession with aesthetics just takes away from practicality.
