Think about it. If the Vectrex had had a raster display and been named the Rastrax, GCE would have sold several hundreds of millions of units and bought up Atari. It would have replaced the 5200, 7800, XEGS, Panther, and Jaguar across several generations. Nintendo would only have been able to license and distribute it in Micronesia, and the Famicom would never have come to fruition.
Sega would have licensed its smash arcade game Subroc 3D as a Rastrax exclusive for use with the 3D Imager, and would have stayed a third-party publisher, never venturing into the console hardware market. Berzerk and Scramble would have been ported with pixel-perfect precision to the platform, and Star Trek: The Motion Picture would have achieved sales success that made the entire Pac-Man merchandising empire of the time look like an insolvent lemonade stand.
Microsoft would have given up on the IBM PC platform, instead seeing the advantages of the 6809 CPU. They would have shifted all development focus to OS9, thus turning the Rastrax into the world standard for desktop computers. Also, Sony would have never made the PlayStation, instead developing a CD add-on for the Rastrax that would have become the real iPod a couple of decades later.
Right now I'd be typing this on the keyboard of my RastraxBook Pro, too.
