Mail Mania is basically a standard photo frame that can wirelessly communicate with a USB dongle in a PC. So when an email is delivered to the PC, this is immediately indicated on the the photo frame by means of a flashing LED. This means you can have the PC in a bedroom or study room and still be informed about an incoming email when you are in, e.g., the living room. Mail Mania is a Plug & Play system, so two buttons have to be pushed only once to pair the photo frame with the USB dongle.
Because of its low cost, the Mail Mania photo frame is also popular as a promotion gadget.
