That didn't happen with IE6. I think the web as platform is bigger than Apple as big as it may be. It's amazing to me that you're OK with a single company holding back the entire platform because of a single device. People use the web with machines that don't even have batteries.
Really to a developer who cares about the open web and standards, just throwing the whole concept of the web out of the window for the sake of Apple's priorities is so, so bad and it will never happen. At least that's my hope and prediction. The open web as a platform will guide my behavior with regards to how I engineer applications that run in the browser, whether Safari is on board or not.
