>> Apple's version of Safari will remain versions ahead of UIWebView meaning that any non-Safari browser will remain inferior by intentional design.

My hope is that deep-linking can make this somewhat irrelevant. If you can deep link to Safari from where you'd otherwise use UIWebView, and design a system that allows you to return to the app you were in when you finish (an easy one, like letting the back button take you back to the previous app), then a lot of these issues are somewhat solved.
