For the same reasons almost all embedded products are PC centric, even though the PowerPC is a better embedded architecture, most platform dependent designs incorporate an Intel processor. It's what the engineer knows. If Apple would promote design software packaged for the engineer into a killer design application, it would encourage a wave of Macintosh friendly products in the immense embedded market of the very near future. The market, such as it currently exists, for scientific software may seem remote from the platform wars of the desktop, but infiltrating the universities and high-tech corporations with killer applications that make scientific research easier and more productive can steer an entire generation of technical leadership in Apple's direction. The Graphic Calculator that ships with every Macintosh, is today mostly a novelty, but it is an example of software that, with further refinement, could find its way into the arsenal of every future technologist.
Small business offers many opportunities to leverage a niche market.
Every purchase becomes an advertisement for Apple and a benefit far beyond the revenues directly obtained. Leveraging influential markets with high visibility could work in surprising ways. A dedicated reception desk package with appointment scheduling, personnel tracking and a phone directory might help put a Macintosh in the lobby of hundreds of companies. That is leverage. A special Macintosh package equipped with the world's best software for stock market analysts.
