The iMac G4 is an example of the work of British industrial designer, Jonathan Ive. Ive is internationally renowned as the principal designer of the original Bondi Blue iMac G4.

Ive joined Apple in 1992. He became Vice-President of Industrial Design in 1998, the year after Steve Jobs' return to Apple.

Ive was involved in the design of such items as the PowerBook G4, the iBook and the iPod.

This was the first all-in-one computer that did away with cathode ray tubes (CRTs) and was therefore a step towards Apple being more environmentally aware.

This computer represents a developmental phase that succeeded the egg-shape of the iMac G3 series and is notable for the shape of its CPU and for the design of the articulated arm that supports its newly introduced LCD monitor. Apple advertised it as having the flexibility of a desk lamp and it was also nicknamed the 'iLamp'. Its design was superseded with the introduction of the iMac G5 in 2004, which incorporated the CPU behind the LCD monitor in 'tablet' form.
