As an owner of an XPS 13, just pick up one of the 1080p (4K is really unnecessary at a 13" screen size) Windows models, re-partition it to give windows a tiny slice of the drive, and install Ubuntu. Linux desktops have been pretty good for awhile now, and Ubuntu has fantastic support for consumer level daily use.
Yeah, 4K is nice but it's not a selling point, I'd rather close the lid and use an external monitor anyway.
I'm sure Ubuntu support is quite good, but I don't really like Linux as a desktop OS and I have gear and software that won't work on it.
Thanks for the suggestion! I would keep it in mind in case I get a separate "work computer" (but I've managed so far with only one computer and a backpack to carry it).
