Dell computers aren't exactly known for having great Linux hardware support or compatibility. Especially in dual graphics switching units like the XPS15....and even worse. Nvidia GPUs. I'm also not sure how Linux is with the M.2 PCIe SSD that this is using or its system support for NVMe. The precision touchpad, keyboard backlight also worry me in terms of how Linux will be around it. I'll be installing Ubuntu 14.04 in the comming days so I can let you know.
