Vavolo four-in-one mouse

Chinese company Vavolo claims to have a product which goes beyond other multifunction mice, offering not just two or three functions, but four. Despite its name, the PCPAL 3-in-1 can be used as a mouse, a keypad, a laser pointer and a remote control, the latter two functions being intended for digital slide (e.g. PowerPoint) presentations on Mac, PC and Linux machines. Controls include Start, Stop, Escape, Page Up/Down and more. The mouse slides into a PC Card slot when not in use. Mac and Linux requirements for the PCPAL haven't been specified, but Windows computers must be running 98SE or later. The product is on sale at the moment for $40.
