iMac Retina 4K 21.5 inches, late 2015

From the 1998 "Bondi Blue" cathode ray tube model, designed by Steve Jobs and Jonathan Ive, to the most recent iMac pro, the iMac is Apple's best-known and most iconic computer. Since the CRT-based iMac G3, its design has evolved from the sunflower-like iMac G4 to today's flat screen models.
