Apple just released its fastest iMac ever has focused on its display and also included a very unique mouse that is totally filled with the touch sensation. The new mac has a screen of 21.5 or 27 inches with 16:9 display. It now offers more speed, memory and enhanced advance graphics. Hidden behind the glass display at the top of iMac is an iSight camera. Which can be used with iChat, and you can be anywhere without actually being there.
Full brightness with no waiting. That’s the big advantage of the LED-backlit iMac display. Unlike most displays that take time to warm up before they reach maximum brightness, an LED-backlit display is instantly on and uniformly bright. LED backlighting also gives you greater control over screen brightness.
The 21.5-inch, 1920-by-1080 display has 17 percent more pixels than the previous 20-inch iMac. The 27-inch, 2560-by-1440 display has a whopping 78 percent more pixels than the 21.5-inch iMac. And a 1000:1 contrast ratio gives you more vibrant colors and blacker blacks. All that in a widescreen display with a 16:9 aspect ratio. The new IPS gives you a bright picture with excellent color consistency — even if you’re viewing the display from the side.

The 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.¹ 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.
