Apple Mouse

Perhaps the single most important feature that sets mice manufactured by Apple apart from others is the emphasis on a single button control interface. It was not until 2005 that Apple introduced a mouse featuring a scroll ball and four programmable "buttons." All mice made by Apple contained a ball-tracking control mechanism until 2000, when Apple introduced optical LED based control mechanisms. Apple's latest mouse uses laser tracking. ... All of Apple's Bluetooth mice have cross-compatibility with almost every Bluetooth capable computer, though they are not supported by Apple for use on PCs. Apple's USB mice likewise are compatible with nearly all USB equipped machines. [Apple Mouse. Wikipedia]
