Micro-HDMI is the de-facto mobile internet HDMI connector.  Obviously part
of that is due to size, but I also feel that the connection was designed to
stand up to use in a device that can be moved around a lot, i.e. Mobile
Phone, or Tablet.  I think you see this in how the connectors are built.
 Because the connection itself is smaller it allows the cable manufacturers
to make the plastic cover for the plug thicker.  This gives additional
support against the outside of the case and helps minimize the force that
is put on the connection between the micro-hdmi port and the motherboard
when the plugs is levered.

Personally I like the micro-hdmi connector because it also stands out and
makes it obvious that it is not another USB port.

I am sure the hardware team will have a lot of other more technical reasons
for the choice.  These are just my personal viewpoints about why I liked
the choice of a Micro-HDMI port vs. a Full size port.
