Aluminum IMac
In August 2007, Apple introduced a complete redesign of the iMac, featuring an aluminum, glass and plastic enclosure. There is only one visible screw on the entire computer, located at the base of the iMac for accessing the memory slots. The back is no longer removable and is now a continuation of the aluminum body from the front and sides. The 17-inch model was completely removed from the lineup.
In March 2009, Apple released a minor refresh of the iMac line. Changes included a fourth USB port, removal of the FireWire 400 port, and a slightly redesigned base. The exterior design was almost identical to the older Intel-based iMacs. The models were one 20-inch configuration and three 24-inch configurations (instead of two at each screen size as before).
Apple doubled the default RAM and hard-disk size on all models, moving the RAM to the DDR3 specification. This revision also introduced a new smaller and more compact Apple Keyboard that excluded the numeric keypad and forward delete key in favor of the fn + Delete keys shortcut.

Famous quotes containing the word aluminum:
“With two sons born eighteen months apart, I operated mainly on automatic pilot through the ceaseless activity of their early childhood. I remember opening the refrigerator late one night and finding a roll of aluminum foil next to a pair of small red tennies. Certain that I was responsible for the refrigerated shoes, I quickly closed the door and ran upstairs to make sure I had put the babies in their cribs instead of the linen closet.”
—Mary Kay Blakely (20th century)
