Apple IMac Design - iMac sets new standards for elegance and power. It packs a complete, high-performance computer into its all-in-one design. With its anodized aluminum frame and glass cover, it’s striking to behold. The glossy widescreen display — available in 20- and 24-inch sizes — makes photos and movies come alive with rich color. The use of recyclable glass and aluminum makes iMac friendlier to the environment, too.
