The Lisa was Steve Job's pet project until he switched to the Mac (oh, Steve, how mercurial you can be!). It was a revolutionary device that didn't sell well for the same old reasons: lack of software, and price.
However, Apple did try and sell a boatload of them (I mean, they wanted to make money). Charles Eicher has spent some time scanning in a Lisa marketing brochure so that we could all look back and ponder a world that might have been.
