This looks like a neat mini PC. It sort of reminds me of those mini PC with a HDMI port on the side sort of like the Chromecast or Roku.
I wised the Compute Card PC had more ports like USB ports for keyboard and mouse, and HDMI port, so I can plug it into older monitors, and TVs instead of buying a new monitor, or adapter to make it work on a TV and monitor with only HDMI, VGA, and DVI.
I agree, soon we will someday be carrying our computers in our back pocket, and maybe even as a belt buckle, key chain or bracelet worn on our hand and neck as a necklace.
