A patent application doesn't guarantee that an idea will turn into reality, but a recently published Apple patent application definitely has everyone daydreaming anyway. It suggests that Apple's exploring the concept of a Magic Mouse with a built-in display.
Actually, the patent application discusses a Magic Mouse with either an "an OLED or specialised display surface made of collimated optical glass that contains a unique magnifying capability". This means that the gadget could either serve as a really expensive magnifying glass or as a customisable mouse with virtual buttons. [Patently Apple via SlashGear]
