At A Glance

Introduced in October 2005, the refurbished iMac line now comes with a built-in iSight camera plus a remote control. The latter comes in handy with a news software program that comes preinstalled on the iMac -- Front Row, a digital media application for playing back movies, DVD, QuickTime movie trailers, and video downloads from the iTunes Music Store. Photo Booth, another newly installed app, lets users take pictures with the iSight and edit them. In addition to a faster processor and frontside bus, this new iMac also ships with a Mighty Mouse multi-button mouse. In February 2006, Apple cut the price of this iMac G5 model by $200 to $1,499.

The iMac G5 is a computer completely built into a flat-panel monitor. This model, which has a 20-inch display and a 2.0GHz G5 processor, is in the top of the line of the second iteration of the iMac G5, introduced in early May 2005. It includes a base of 512MB of RAM and built-in AirPort Extreme and Bluetooth 2.0.

The most distinctive changes to the iMac line come on the outside -- the desktop now sports an aluminum enclosure that resembles what you might see from the Mac Pro or MacBook Pro. The 17-inch offerings are gone, replaced by a pair of 20-inch models and a 24-inch iMac, each with a glossy wide screen. Other changes are more modest -- the low-end iMac now runs on a 2GHz processor, instead of 1.83GHz. But all iMacs now feature a FireWire 800 port and can support up to 4GB of RAM.

In this third-generation of aluminum iMac models, the lone 20-inch model features a 2.66GHz Core 2 Duo chip, a maximum of 8GB of memory (it ships with 2GB), a 320GB hard drive and integrated Nvidia graphics that share memory with the system RAM.
