In October 2009, Apple unveiled the new 21.5" iMac. Externally, the machine features edge-to-edge glass and an aluminum rear bezel. Internally, an LED display, 4 RAM slots (to upgrade to a maximum of 16 GB RAM), more powerful video processing, and faster processors round out an impressive upgrade from the most recent 20" iMac.
