He aint heavy, he's my laptop

Excuse me, but when did four pounds not including battery become "pretty light" for a laptop? My current laptop is under four pounds without battery and barely over with the extended battery and it is over two years old to boot. So shouldn't a state of the art laptop be less than four pounds with battery if it is to be classified "pretty light"???

My only conclusion is that a spate of monster arm breaking laptops with 17 inch screens and masses to match has warped our sense of what is or is not "pretty light".
