In 1998, the computing public learned that computers no longer had to be beige: Jobs introduced the iMac onto the desktop scene in a rainbow of colors. The original iMacs came with a 233 MHz PowerPC 750, 32 MB of RAM, a 4 GB hard drive, a 24x CD-ROM, ethernet, stereo speakers and a 15-inch monitor. The only items not encased in the egg-shaped chassis were the keyboard and the mouse. The iMac quickly became the fastest-selling personal computer in history.
Two years later, Jobs launched Mac OS X, Apple's operating system which is based on the NeXT OS.
