Somewhere around 50x is the dividing line between "I want to see normal stuff really up close" (best done with a stereo microscope or camera with macro lens [some "digital microscopes" fall in this realm]) and "I want to see microscopic things that are invisible to the naked eye" (best done with a biological style/compound microscope with stage and slides, etc.). They can both be interesting! The Foldscope is definitely aimed at the latter case.
