People — developers — aren’t just numbers. They have tastes. They have biases. If they didn’t, then all the great iPhone apps of 2008 would have already been written for Symbian, PalmOS, BlackBerry (J2ME), and Windows Mobile years earlier. If they didn’t, then all the great Mac apps would have been migrated to Windows a decade ago.
Mobile isn’t desktop, and 2014 won’t be 2008, but it’s hard to imagine at least some of the same forces that applied to desktop and the early days of mobile won’t also apply now and into the future.
This is also why companies that try to beat developers over the head or pay little bonuses to write for their platform don’t understand developers and won’t attract the best ones.
