Updated today, I gave the brand new version of Opera Mini a spin on my Lumia 930:
It's a clean look, albeit with some on-screen furniture. Unlike Internet Explorer, tables are handled properly too, for general purpose browsing this looks ideal.
The central Opera control in the bottom toolbar brings finger-friendly icons to the main functions, plus a handy 'data savings' gauge (note that this can be expanded to a full-screen chart, plus you can customise the image quality being grabbed to improve the compression ratio overall still further)...; (right) switching between tabs
The Settings pane has been made much simpler than in previous betas and on other platforms - easy to understand and not much to fiddle with! (right) highly interactive sites - including Disqus!! - fall foul of the proxy server-based approach, but you can't have everything...
