What sucks about snow shovels?
pg: For me the biggest problem with the classic snow shovel is (was!) that it's not good with ice.  It assumes powder.  It also assumes a flat surface.  So it's good for shoveling newly fallen snow off a concrete suburban driveway, but lousy for clearing a Cambridge sidewalk.Maybe you could design an urban snowshovel.   It could be narrower and heavier, like a regular shovel.
