I recently bought a Dell XPS 15 with the quad-core Skylake i7, 4K UHD screen, 256GB PCIe SSD, GeForce GTX960M GPU and 16GB RAM. With discounts and everything, I was out the door at just over $1,700.

I was still curious about the new MBP, though (still within my 30-day return window with Dell), and finally got all the details yesterday. It turns out a comparably equipped MBP would run north of $900 more (including tax and the other dongles/adapters I'd need). I think the total was around $2,600. That's for a 15-inch screen, the quad-core Skylake i7, 256GB SSD, Radeon Pro 450 GPU and 16GB RAM.
I'm not a fanboy for either company. I've owned both Windows and Mac machines and was genuinely considering the MBP. But I just don't know how to justify that much extra cost. So Apple has lost me as a potential customer (for now). We'll see what the refurb market looks like next year though.
Also, for the record, I've been running on Windows machines for 15 years and have never had a virus or catastrophic data loss. I think it's an easily avoidable issue caused by people carelessly clicking every link they see pop up on the screen. Kinda like cars...people don't take the time to learn about them and maintain them, and then they complain when things break that wouldn't have with proper maintenance. Anyways.
