#11 Macintosh Portable: 1989

Released on September 20, 1989, the Macintosh Portable was Apple 's first battery-powered portable Macintosh personal computer. It was also the first commercial off-the-shelf portable computer used in space and the first to send an email from space, in 1991 aboard Space Shuttle mission STS-43. It featured a fast, sharp, and expensive black and white active matrix LCD screen in a hinged design that covered the keyboard when the machine was not in use. The Portable was perhaps the first consumer laptop to employ an active matrix panel and the cursor pointing function was handled by a built-in trackball that could be removed and located on either side of the keyboard.

10 Macintosh Quadra 700, 900: 1991

The Macintosh Quadra 700 was introduced along with the Quadra 900 in October 1991 as Apple's first computers to use the Motorola 68040 processor, as well as the first to feature built-in Ethernet networking as many Unix workstations did.

The Quadra 700 could be upgraded to 68 megabytes of RAM, which with its 25 MHz processor made it a very useful computer for scientific or design work.

The Quadra 900 was more expandable than the Quadra 700, up to 256 megabytes of RAM—an astronomical amount for the time.
