The Mac, though its market share was never large, especially when compared to the well over 90% marketshare of Microsoft Windows-based PCs, had always attracted an incredibly talented, incredibly dedicated group of developers who cared deeply about things like design and user experience. OS X enjoyed not only the traditional Mac OS community, but the NeXT one as well. That talent share always felt disproportionate to the market share. Massively. And a lot of those developers, and new developers influenced by them, not only wanted iPhones and iPads, but wanted to create software for them.
