As a long time Opera user, I've moved with the versions with generally very little angst. One small niggle for a little while has been that often now, the full URL is hidden until you click in the address field, occasionally this can be a PITA. However, overcoming my inertia I discovered the preference setting in "Browsing": Show full URL in address field" which fixes that. And of course, with Opera Link enabled, the settings are carried over to every other instance of Opera if you want (along with bookmarks etc).
