i'm quite happy with the xps 13 developer edition and debian testing.

hidpi is not handled well in some (or many) applications, but the window manager (or linux as a kernel) has no problem with it. (and i still have very good eyes)

the usb-c dell adapter works perfectly (hdmi, vga, ethernet), i get up to 8 hours of battery, it's light, solid, quite and fast...

just a bit hot when charging.

the only big issue that i have still to solve is, getting a second monitor to work (mirroring somehow works)... but this is what you get when you don't use a destkop environment and have just a minimal install... (the ubuntu that comes pre-installed has no problems with the external monitor)
