Apple memorably unveiled the Macintosh in 1984 and proceeded to build a hard-core following of customers who appreciated good design and were willing to pay premium prices while overlooking any interoperability issues with Windows - a factor that Apple has subsequently addressed with its OS-X operating system. Amongst a wealth of innovations introduced over the years, the radical, all-in-one design of the iMac was one turning point, bringing colour and light to the drab world of computing. The same lateral thinking and attention to detail has been applied to products such as the original iPod in 2001, the PowerBook in 2003, Mac Mini in 2005 and, in 2007, the iPhone.
