This is the best summary yet of the dangers facing the Mac, but I still don’t think it goes far enough. While removing power user features like metadata editing and smart playlists is annoying, what’s really going to blindside Apple is losing software developers, and then, designers—in other words, the people who make software. For years Apple has had stranglehold on them because they’ve provided great GUI tools with Unix underpinnings (for developers at least). But both of these areas have been neglected for a decade, by focusing on UIKit instead of AppKit, and letting the Unix underpinnings rot. A funny thing happens when you stop moving forward, everyone else catches up.
