But that is my point - if you force your customers to such a position, albeit for plausible security reasons, you better make sure your browser is top of the game.
I still very clearly remember when Jobs showed everyone that you can have a Real Browser in your palm (as opposed to WAP-somethings). You could hear jaws dropping around you. It was glorious! I do not think you get a proper browser with iOS these days. The world has started to be "optimised for Chrome" and this sucks.
