As a quick example.

(DUAL floppy drives !!)
I looked the Thinkpad up on a Danish online shop and what I see is a price of 19499 Danish Kroner and the specs of the machine is
i7 -5600U dual core 2.4Ghz. 512GB SSD (interface not specified). NVIDIA Quadro K620M / Intel HD Graphics 5500
Weight 2,3kg, dimensions 38x25,8x2,2cm
The similar MacBook Pro for Denmark is: 21499 DKK and specs:
i7 2,5Ghz quad core, 512GB SSD PCIe (almost 2GB/s benchmarked). Intel Iris Pro Graphics/AMD Radeon R9 M370X 2GB
Weight: 2kg, dimensions 35,8x24,7x1,8cm.
So the main difference is a dual core machine compared to a quad core and a slimmer and lighter design of the MacBook Pro, not to mentioned design simplicity and elegance. But that's a personal taste, of course.
If you ever consider buying the Thinkpad, then try the trackpad first and compare to the MacBook pro trackpad. On my workshops I have people who need help on their Windows laptops and it always surprises me how bad the trackpads on the Windows laptops are. On the MacBook the trackpad just works really well. I never even bring a mouse with me for the MacBook when I travel. In my office behind a big screen, keyboard I use the Apple Magic Mouse. I would also recommend to try out how well the Windows laptop handles multiple displays. The MacBook can out of the box handle up to two external 4K displays in addition to the built-in display.
I'm sure one can get used to Windows laptops again but in my opinion they should be a lot cheaper and be built as well as the MacBook for me to ever consider one

But this is just me.
