I concur, as a Windows Mobile user (Blackjack II) I downloaded Opera to 'try' and use it occasionally on websites which I know render correctly/better than mobile IE. However much of the web is not Opera Mini compat, and it tends to freeze/screw up quite frequently which forces me back into the mobile IE ghetto.

However it's worth noting that I just installed Skyfire is it's working beautifully.

Shows web pages like a desktop browser (no one-column BS), has Opera/Safari-esque zooming features and plays web video (YouTube/ESPN) with no fuss. Lovin' it.
