Connectivity includes four USB 2.0 ports, a Firewire 800 port, built-in AirPort Extreme, and Gigabit Ethernet, as well as a Mini DisplayPort, which supports an external display in extended desktop mode.

The iMac Core 2 Duo (Early 2009) models are quite similar to the Early 2008 models that they replaced, with similar external cases -- varying only by a tapered foot -- and likewise have the same glass cover that joins precisely to the aluminum enclosure creating a virtually seamless front surface.

Although clockspeeds and configurations are similar as well, there are a few differences -- the Firewire 400 port on the Early 2008 models has been swapped for an additional USB 2.0 port on the Early 2009 models, Mini-DVI has been swapped for Mini DisplayPort, and the 2009 models also have DDR3 memory (rather than DDR2) with twice the official capacity, improved graphics on the higher-end configurations, and by default, shipped with a smaller keyboard that lacks the numerical keypad.
