Mobile Chrome's networking stack is the same as Desktop Chrome, providing SPDY, prefetching, etc.
That said, there is a lot of code we do leverage, such as the network layer, the sync and bookmarks infrastructure, omnibox, metrics and crash reporting, and a growing portion of content."
Only 2 things I don't like about it:
1) Getting at bookmarks requires too many clicks.
2) Sometimes my bookmarks get rearranged on the desktop after I use them in iOS.
Otherwise, great job. Syncing my browser history/bookmarks/passwords is great. And it feels more snappy than Safari, which I didn't think was even technically possible.
I guess you could download the HTML externally and get it into the view through loadHTMLString:baseURL: , but that would still make the UIWebView load all images etc.
