Om Malik of Business 2.0 says startup companies that launch their products only for Windows-based PCs are missing a big opportunity. “I think these companies are focusing too much on the numbers and missing the more promising opportunity,” writes Malik. “Why? Because rolling out a product for the Mac platform ensures a certain buzz and élan, which begets more buzz, which begets sales. Let me explain. By some estimates there are 5 million active Mac users. Not a lot, that’s for sure. But among them are most of the influencers — high-profile bloggers, most (if not all) technology journalists, and, of course, the hipsters.”
