You could also find a niche market that has little to no competition and develop to that. I remember when the Desktop Publishing market was new, and the Commodore Amiga had Deluxe Paint and a few third part desktop publishing apps in 1985. Then later in Adobe made Photoshop in 1989 for the Macintosh that copied the ideas of desktop publishing software on the Amiga. Not only that but Newtek had a Video Toaster and Video Editing software for the Amiga, and later on Apple copied it with iMovie and other stuff. But back in 1985 it was a small niche market, and it grew so much that it migrated to the Macintosh and became best selling products that promoted the Mac over the PC.

The Amiga was basically a launch platform that went away for many niche market software. If the companies that developed those for the Amiga had developed them for the Macintosh, they'd still dominate today.
