Sadly, I'm actually about to sell the XPS 13 that I've got.  Xorg 
appears to have a bug in handling Fn+arrow for Pg up/down, which causes 
it to key-repeat pg up/down until interrupted.  The trackpad is just 
awful.  Click is frequently interpreted as right-click and middle-click 
emulation is extremely unreliable.  The mouse cursor also frequently 
jumps when clicking.
