powerbook 100

Before the powerbook 100 portability was relative. Those who could afford a mac plus (1986) or a macintosh portable (1989) could already reach before 1991 in the possession of a mobile mac.

But the first truly portable mac was just the powerbook 100.  A floppy drive was the only external (the macbook air says hello from the distant future) but the powerbook 100 came with a portable LCD display with backlight, a 16 MHz CPU 68000 and long battery life.

The powerbook 100 was designed and manufactured by sony.  $4,000 cheaper than the macintosh portable, a third of the weight as slowly and no internal floppy disk drive - with this recipe took apple the next start-up. The powerbook 100 has received relatively good reviews, found numerous customers and coined a product name, apple retained nearly 15 years.
