iMac G4

iMac G4. The iMac G4, often nicknamed the "iLamp" or "Sunflower iMac," was a groundbreaking all-in-one personal computer introduced by Apple Inc. in early 2002. Designed by Jonathan Ive and his industrial design team, it famously replaced the colorful, bulbous iMac G3 with a radically new form factor centered on a flat-panel display suspended from a polished hemispherical dome. This model marked Apple's full transition to the PowerPC G4 processor and was pivotal in popularizing the LCD monitor in the consumer desktop market.

Design and hardware

The most iconic element was its articulated arm, allowing the LCD screen to float and swivel with remarkable flexibility, a feature inspired by the Tizio lamp designed by Richard Sapper. The hemispherical base housed the main logic board, optical drive, and connections, creating a minimalist footprint. Initial models featured a 15-inch screen, later expanded to include 17-inch and 20-inch versions, with the larger displays utilizing more advanced Apple Cinema Display panels. Hardware configurations varied, offering combinations of CD-RW and DVD-R SuperDrive options, alongside AirPort 802.11b wireless networking and Bluetooth as build-to-order features. The enclosure, made of polycarbonate and acrylic glass, was produced in stark white, aligning with Apple's then-emerging aesthetic seen in products like the iBook and iPod.

Software and operating system

The iMac G4 shipped with Mac OS 9 as the primary bootable operating system, with Mac OS X version 10.1 "Puma" included and easily installable, reflecting Apple's ongoing transition between platforms. Key bundled software included iTunes for music management, iMovie for video editing, and iPhoto for digital photo organization, part of the expanding iLife suite. Later models, such as those released after Macworld Conference & Expo events, came with newer versions like Mac OS X Jaguar and Mac OS X Panther pre-installed, taking full advantage of the Quartz graphics system and OpenGL support. This era also saw the introduction of applications like Safari, which replaced Microsoft Internet Explorer for Mac as the default browser.

Reception and legacy

Upon release, the design was widely praised by publications like PC World and Wired for its innovation and elegance, though some critics noted its premium price compared to Windows XP-based desktop computers from Dell or Compaq. It won numerous design awards, including accolades from the Industrial Designers Society of America. The iMac G4 is remembered as a landmark in industrial design, successfully translating the consumer-friendly ethos of the iMac G3 into a sophisticated, flat-panel era. Its influence is evident in later Apple products and competitors' designs, cementing its status as a collectible icon. The model was succeeded in 2004 by the slimmer iMac G5, which integrated the PowerPC G5 processor and moved the entire computer behind the display.

Technical specifications

The line was powered by PowerPC G4 processors from Motorola, starting at 700 MHz and eventually reaching 1.25 GHz. System buses operated at 100 MHz or 133 MHz, paired with PC-100 or PC-133 SDRAM expandable up to 1 GB. Graphics were handled by Nvidia or ATI Technologies GPUs, such as the GeForce2 MX or Radeon 7500, with dedicated VRAM. Storage options included ATA hard drives ranging from 40 GB to 160 GB. Connectivity comprised USB 1.1, FireWire 400, 10/100BASE-T Ethernet, and optional AirPort and Bluetooth modules. The built-in audio system featured Harmon Kardon speakers, and the computer supported resolutions up to 1680x1050 on the 20-inch model.

Development and release

The project, codenamed "Cosmos," was developed under intense secrecy by Apple Inc. following the success of the iMac G3. Its development paralleled work on the Power Mac G4 and the professional Apple Cinema Display line. Steve Jobs unveiled the iMac G4 on January 7, 2002, at the Macworld Conference & Expo in San Francisco, emphasizing its design as the "digital hub" for the burgeoning digital lifestyle. Subsequent revisions were announced at later events, including speed bumps and the introduction of the 20-inch model in 2003. Production ended in mid-2004 to make way for the next-generation model, with the final units sold through the Apple Store and authorized retailers like CompUSA.
