Daring Fireball: “The whole point of Appleâ€™s success with iOS has been the opposite of â€œwrite once, run anywhereâ€. Itâ€™s more like â€œwrite a version that is specifically optimized for this particular deviceâ€.”
This is one of the things I love about Apple. A lot of companies would be fine with slapping some simple mouse based helpers into their emulator, change it ever so slightly so it works on the desktop, and ship it. Apple doesn’t do that. They tune their software for the hardware platform. As it should be.
