Cons
Con Intel is a bitch
For an M2-port, HDR, better GPU power or more RAM support Intel wants you to buy the much higher priced iX-based models even if HDR would be possible on Atom GPU's.
Con Requires 15V power supply
12V 5.5/2.2mm barrel supplies are everywhere, but it should 1up with USB C power input instead.
Con Only one USB port and does not like power cut
Better to use a small UPS and keep a SD card with the flash boot installed.
Con Boot button is on bottom
Makes it more difficult to access when drives are installed, as opposed to on the back, sides, or front.
