I have a new XPS 13. It's impeccably built, you can use it comfortably on an airplane, and it runs Linux with no issues. But I wouldn't use it for daily development. The 13 inch screen just doesn't have enough real estate, and it often feels like it's struggling to drive the 4k screen whenever I try to switch applications. If you don't mind something heavy, check out the new Thinkpad P50 or P70. They have actual desktop-level performance, terrific screens (matte, color corrected 4k IPS!) and the new NVMe SSDs. I do most of my daily development on a P70, and increasingly just lug it along when I travel even though travel was the reason I bought the XPS 13.
