I usually think of "subnotebook" as implying the keyboard is undersized; a thin and light machine that is still wide enough for a standard keyboard layout is something else.
I think we should bring back the term "luggable" for those mobile workstations and gaming notebooks that are hot, heavy, have 2hr or less of battery life.
