I think the point is that although you can install another browser, you can't set it as "default" -- links from other apps, from Mail, etc. must open in Safari unless the other browser is hardcoded into the app (like "Open in Chrome" menu items). Having an ability to set default apps would make iOS significantly more sophisticated, in my opinion.

A good reason for jailbreaking is to allow you to set any browser as the default browser and allow any 3rd party UIWebView application the ability to use the Nitro JS engine that Safari uses.

My default browser on iOS is Chrome and it runs as fast as Safari.
