This nicely highlights a problem I see with controlled app store models. I would like to give this a try but looking at reviews I feel like I might not like it (always visible address bar, bigger text). So I might want to downgrade which is not "allowed".

I am glad they let users move the navigation bar to the bottom, that is much easier to reach with one hand.

I wish there were site specific preferences like on the desktop version. Being able to block image loading for selected websites or forcing a css mode would greatly reduce my bandwidth costs and increase readability.

A great feature of Opera Mobile is that you can save pages for later offline reading.
