USB 2.0 | 15-inch Flat Panel | 1GHz

Seven months have passed since the introduction of the 17-inch 1GHz iMac. A milestone processor reserved for the high-end then, it now resides inside the base model of the USB 2.0 series.

This model is powered by the G4 1GHz processor with AltiVec “Velocity Engine” and offered a number of improvements over the second generation 15-inch Flat Panel iMac it replaced.

This model probably represents the last iMac to be offered in 15-inch. The future and ever larger displays beckoned.

The price and the amount of memory remained the same but the memory is now 256MB of PC2700 (333MHz) DDR SDRAM instead of 133MHz SDRAM.

In addition, the frontside bus rose from 100MHz to 133MHz and hard drive capacity grew from 60GB to 80GB. It used the same 32x Combo drive as its 15-inch predessesor, but opted for the more powerful NVIDIA GeForce4 MX graphics processor with 32MB of DDR SDRAM instead of the GeForce2.

This model came Airport Extreme ready with a build-to-order option for an internal Bluetooth module. There were two FireWire 400 ports, three USB 2.0 ports (two more USB 1.1 ports on the keyboard), a VGA output port, built-in modem and Ethernet, S-video and composite video output, headphone jack, Apple speaker minijack and audio line-in jack.

This series shares the rear port rearrangement of the previous 17-inch 1GHz model, except with USB 2.0 ports rather than 1.1.

All models in this series came with the Apple Pro Keyboard, Apple Pro Mouse and Apple Pro Speakers.

This was a long-lived series and deservedly so. Almost a full year would go by before these beautiful floating display models would be superseded by the G5 iMacs introduced on August 31, 2004.
