Apple is always revealing new computer gear and technological products through their Macworld Conference and Exposition and in January 2005, they unveiled the Mac Mini. At 6 1/2 inches and standing a height of only 2 inches tall, the Mac Mini introduces computer users to a small, compact model. The Mac Mini is a full desktop computer that comes minus a keyboard, monitor, or mouse. Those who will easily connect it to other computer peripherals use it. The MacMini is available in hard drive capabilities ranging from 40 to 120 Gigabytes and can be upgraded. With the wide variety of products available from Apple, PC users should not feel intimidated by the world of Macintosh, but rather embrace this ever-growing line of computer technology.Choose the imac that meets your needs at http://www.electroland.gr/apple-mac.htm
