iMac: This is the computer that reversed Apple's fortunes. Released in 1998, the original iMac was a radical departure from other computers of the era. Instead of a tower desktop and a bulky CRT, the iMac was a sleek all-in-one desktop, clad in turquoise and white translucent plastic (Apple referred to the colors as "Bondi Blue" and "Ice," respectively). It also had no floppy drive (gasp!)--a sign of things to come, perhaps. Thirteen years and many revisions later, the iMac lives on as Apple's flagship desktop Mac.
