After all, Windows 10 isn't the most touch-optimized operating system, with both Store and traditional desktop apps, for the most part, better used with a keyboard and mouse pointer. However, even the touch models don't officially support a digital pen, so you're not gaining a whole lot of functionality by being able to jab at your laptop screen with your fingers.
The quality of Dell's displays is excellent, whichever you go for, with exceptional brightness and color reproduction across the board. The 4K display with touch is also an option now, as is a 3.5K OLED touch panel, but these come standard on higher-end models in the range, though you can opt to spec it down to a 1080p on some models.
The standard choice is the 1080p non-touch display, but this can be configured to a 1080p touch version for an additional $100. It shouldn't be any surprise, but having the Dell XPS 13 with a touchscreen will cost you more than if you go for one without it.
