The Apple iMac 20-inch Early 2008 is a personal computer produced by Apple from 2008 to 2009 as part of the iMac series. Launched on April 28, 2008, the starting price for this model was $1,199.

Apple revamped its all-in-one iMac lineup, equipping it with the latest Intel Core 2 Duo processors and the most robust graphics ever seen in an iMac. Starting at $1,199, the iMac boasted faster processors with 6 MB L2 cache, a speedier 1066 MHz front-side bus across the entire line, and 2 GB of memory as standard in most configurations.

Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing, commented, “The iMac’s stunning aluminum and glass all-in-one design has resonated incredibly well with our customers, contributing to Mac sales growing three and a half times faster than PC sales. With the latest Intel processors, enhanced graphics options, and expanded memory, customers now have even more reasons to appreciate the iMac.”

Combining dual-core performance with a sleek all-in-one design, the new iMac boasted faster Intel Core 2 Duo processors across the lineup, a 1066 MHz front-side bus, up to 4 GB of 800 MHz DDR2 SDRAM memory, and a widescreen flat-panel display supporting millions of colors. Connectivity options were advanced, with built-in AirPort Extreme 802.11n Wi-Fi networking offering up to five times the performance of 802.11g, along with Bluetooth 2.1+EDR, Gigabit Ethernet, built-in iSight video camera, five USB 2.0 ports, and one FireWire 400 and one FireWire 800 port.

Apple demonstrated its commitment to environmental sustainability with the iMac, using highly recyclable and durable materials such as scratch-resistant glass and professional-grade aluminum. Each model in the iMac line was rated EPEAT Silver, and the energy-efficient iMac met the stringent Energy Star 4.0 requirements for power consumption. Additionally, customers could recycle their old PC or Mac for free through the Apple Recycling Program upon purchasing any qualifying Apple computer.

Moreover, each Mac came with Leopard, the sixth major release of the macOS, featuring Time Machine for automated backups, a redesigned Finder for easy file sharing between multiple Macs, Quick Look for instant file previews, Spaces for organizing applications, and Stacks for convenient file access from the Dock.
