OSNews published a link to Forbes article that listed Apple’s failure.
An interresting point there is that OSNews disagrees on Forbes’ point at Lisa as a flop.
Some of the concepts of the Macintosh were pioneered by the Lisa team, such as Quickdraw, one of the fundamental components of the Mac OS. In addition, as the stories on Folklore.org point out, the competition between the Mac and Lisa teams propelled both teams to excel at what they were doing. From this perspective, the Lisa wasn’t a failure at all.
It’s either Forbes doesn’t know this fact, or it means nothing for it. If Lisa doesn’t sale, it’s a flop. Typical of business people’s point of view.
