Just for your information, we don't have a "real" Chrome on iOS, we have UIWebViews with Chrome branding. So Google can only innovate in the UI surrounding the web pages, not the rendering and interaction of the websites themselves.
Not 100% true: iOS Chrome bundles its own networking stack which is a differentiator (it supports SPDY for a start). They are hampered by UIWebView’s slower JS engine though.
Thanks! Was not aware of the networking part, nice to know.
The rendering engine is also much more than "just rendering". When I click two small links close to each other on Android Chrome, a small clickable popup containing a zoomed in portion of that part of the page will appear. Very useful for avoiding misclicks!
