I currently run Debian Jessie on an XPS 13 - GNOME 3 handles high DPI with minimal configuration. I'm sure KDE could manage as well, but I did not have a magnifying glass available to navigate the miniscule menus. I've run into more issues with apps that don't scale - some games and the Arduino IDE being the biggest offenders I've come across. I agree with regard to the touchpad size/palm sensitivity - accidental clicks are a big problem.
