The new iMac features a brilliant 21.5-inch or 27-inch LED-backlit display with a widescreen 16:9 aspect ratio—perfect for watching HD video. The 21.5-inch display offers 1920-by-1080 HD resolution, and the 27-inch display goes beyond HD with 2560-by-1440 resolution. Dual-core Intel processors now start at 3.06GHz, available quad-core Intel processors boost performance up to 2x, and advanced graphics make the most of every pixel. iMac declutters your desktop with the Apple Wireless Keyboard and the new wireless Magic Mouse: the world’s first Multi-Touch mouse. The 27-inch iMac starts at $1699. The 21.5-inch iMac starts at $1199.

LED backlighting.
When a display has more pixels, you need to push more light through them to achieve the best picture possible. LED backlighting in the new iMac does exactly that, with remarkable brightness and efficiency. Because the LED backlight doesn’t take up much space, the iMac enclosure stays thin — even with all the high-performance components inside.

Now available with quad-core power.
The 21.5-inch and 27-inch iMac models offer fast Intel Core 2 Duo processors up to 3.33GHz. Quad-core power comes to the 27-inch iMac with a 2.66GHz Intel Core i5 processor or 2.8GHz Intel Core i7 processor. Four cores deliver up to 2x faster performance for just about everything you do: managing your photos, editing HD video, even playing graphics-intensive 3D games. And since Mac OS X Snow Leopard is designed to take full advantage of Intel dual- and quad-core architectures, you get the fastest performance possible.

More memory and storage.
The new iMac has 4GB of 1066MHz DDR3 memory standard, with room in its four SO-DIMM slots for up to 16GB, so you can run more applications simultaneously. And with a Serial ATA hard drive up to 2TB,² feel free to load up on photos, videos, and music.

Built-in Wi-Fi.
High-speed 802.11n wireless technology is built into iMac. And with Time Capsule or the AirPort Express Base Station, every computer in every room can wirelessly connect to iMac, the Internet, and each other.³ Over this network, everyone can print, surf the web, and play music on iTunes through your home stereo — wirelessly.

Wireless Magic Mouse.
Forget the mouse as you know it. Every iMac comes with the wireless Magic Mouse: the world’s first Multi-Touch mouse. Use it once and you’ll wonder how you ever used anything else. There’s no scroll ball, no clunky wheel, no cord, and no visible button.

Instead, Magic Mouse uses Multi-Touch technology to let you control everything with simple gestures. Give them a try and you’ll find that Magic Mouse changes the way you interact with your computer. Built-in software lets you configure Magic Mouse any way you want. Its smooth, seamless design is ambidextrous, and it supports two-button clicking — without buttons. Like magic.

Wireless keyboard.
iMac banishes desktop clutter completely with a wireless keyboard to go with the wireless Magic Mouse. This low-profile keyboard takes up less desk space — 24 percent less — than larger keyboards. There’s no numeric keypad, so you can place your mouse comfortably next to the keyboard. And built-in Bluetooth means there are no cables to connect.
