I'm currently running LE on a Pi 3 and noticed that the total RAM reported by free -m was only showing 736M. This seems low for a board specced with 1G of RAM. Is the RAM used elsewhere i.e. video memory etc ?
This is what free -m reports on a Pi 3:-
total used free shared buffers cached
Mem: 736 319 417 5 38 139
-/+ buffers/cache: 140 595
Swap: 0 0 0
