Scale is the decision here. A desktop or A3 board suits one person planning a week, a lap board suits a huddle, and neither is trying to replace a wall-mounted board for a whole room. Because these are handled, edge protection and a frame that survives being knocked matter more than they do on a fixed board. Surface still decides ghosting. See whiteboards, mini whiteboards and whiteboard markers.
