How the PowerBook was Born

Sabah Arif writes "Apple had no presence in the portables market prior to 1992. Its attempt at creating a laptop Macintosh, the Macintosh Portable, weighed almost 15 lbs and failed to sell. On the personal behest of John Sculley, Apple contracted with Sony to create Asahi, a smaller Portable. Apple developed two high end models in company. After 1992 and until the disastrous 5300, Apple was the leading notebook maker."
