I have included some screenshots below which show the functionality now available in Iris including Bookmarks, history, password, Incognito mode and even an Inspector. It handles nearly every page I threw at it and the RISC OS integration is really nice. It is slower than Safari on my top of the range Mac, but very usable on my Titanium.
RISC OS Developments have promised us a bit of a special South-West Show and hopefully might consider that an appropriate time for a general release...
