iMac. Design and release The eMac had a substantially similar design to the iMac G3, but featured a larger (16-inch viewable) flat-screen CRT monitor. The larger screen offered 40percent more viewing area than the iMac. Thanks to the short-necked CRT, it took up the same space as the iMac—in fact, it was a few millimeters shorter–but also was heavier, at . The computer was powered by a PowerPC G4 processor much faster than the G3-powered iMacs. The machine's serial number and networking identification were printed on the front of the computer behind the optical drive door to make it easier for schools to track purchases. RAM could be upgraded through a service hatch at the bottom of the computer. Apple sold a separate tilt-and-swivel stand to enable changing the viewing angle of the screen. Release After complaints from customers, Apple announced the eMac would be available through general retail on month later. Regular consumers did not get the same prices and configuration options as education customers; for example, education buyers could get a model without a modem.

The next revision to the eMac line came in April 2004, with DDR SDRAM, a faster processor running at 1.25 GHz, and a better ATI Radeon 9200 video chipset. The most recent revision came in May 2005, with an even faster CPU running at 1.42 GHz, Radeon 9600 graphics, and larger standard hard disk. On October 12, 2005, Apple once again restricted sales of the eMac to educational institutions and returned to its "E is for Education" marketing plan that had been attached to the product from the original restriction to education buyers. The company re-implemented this restrictive measure for unspecified reasons. Some analysts believe Apple wanted to force the general
