It appears that Apple have leap-frogged Google Chrome’s Mac UIattempts and basically implemented what Google Chrome wanted to be on Mac already, with a lot of extra Apple polish. If there were a case for ripping UI off, this would be it. That said, should we complain when it’s done so well?
Just check out the features. I can only describe it as an immense list of awesome. And this is for a browser that only has a mere fraction of the browser marketshare. Clearly Apple have their hearts set on something to put this much effort into their desktop browser.
The web is the platform, and Apple know that if they can’t define it entirely themselves, then they must do their best to make sure everybody else plays fairly. Safari 4 is meant to be an IE6 killer. IE cannot stand up to anything on the market now.
For me, as a web designer (and particularly one developing in HTML5), Safari 4 adds more amazing capabilities to websites than I can even think what to do with. It will be years before we've got our heads out of a spin and really knuckled down to subtle and elegant uses of CSS animation, audio/video and gradients.
But can we learn it and put it to use?
