The high res screen is the reason I switched to macbooks after a lifetime of windows laptops in the first place. I still have and use my 2012 macbook pro retina which is about 6 more years of functional life than I've gotten out of any windows laptop, and it cost the same then as the base XPS 13 does now.

The prices between manufacturers aren't really all that different; but, if they happen to be important for you, Apple has a few features and components that others haven't been able to replicate at any price point, which is why paying the Apple tax is worth it to some.
