I agree with you on all the line.
I'm an Opera user since the first public release. I loved the way Opera innovated and introduced new features release after release.
Now that they moved from Presto to Webkit, Opera has lost all its great features. Dragonfly, linked tabs, all the toolbars we were used etc.
I'm going to use Opera 12.16 until it will be usable and compatible with new web sites, after this it will be a problem because I'm so used to use Opera that every other browser miss something that I'm used to use.
Chrome and Firefox have a bad interface to me, IE is unusable, . . . It's a mess trashing so much work to build its own engine and move to webkit. There are so many browser that uses webkit, Chome and Safari for first that I don't see the reason to do such a move.
Opera R.I.P. , I had great days with you
