So I actually have been actively using Opera for a while now. As well as it having a place in my history as my primary browser back in the day. And by now you might have then inferred that while I use Opera it is not my primary browser. Let me explain.
Since, at least as far as I'm aware, you still can't give a command line options to any Windows browser to tell it where/what size to open it has been convenient for me to use Firefox on my main monitor for my primary browser and then a 2nd browser that opens up on my 2nd monitor. Further it is nice having my 2nd monitor browser be different since then I can keep 2 effective sets of bookmarks. Since my 2nd monitor browser is in effect more a media device than my primary browser.
And for that Opera has worked great. In fact it still is working right now on my 2nd monitor where a YouTube video is playing right now. The UI was decent, it did not eat up a ton of resources, and overall did exactly what I wanted it to do and did it pretty well.
Well just a week ago I wanted to do a reinstall and so I packed up all my programs config/data files and did the deed. Opera's data files sit in:
C:\Users\$UserName\AppData\Roaming\Opera\Opera x64
Notice that last bit...my archive said just Opera not Opera x64 which I thought was a little odd since Opera kept auto updating for me so I thought I was running exactly the same thing that I had been not 45m prior. But whatever, I could see why that could happen between version installs but not updates. I was wrong.
I had been running Opera 12.x. I did not really keep track of it since all the dev's lost their heads and went for version number bloat and all that. So when I hit Opera's download site I just grabbed the latest version, installed, turned it on once, killed it, replaced the default config files with mine, and turned it back on and...
It was like installing Win8. Total UI change for the worse. (This was now Opera 19 btw.) No way to even put up a button for bookmarks. Everything had to go though a "quickdial" type page. Options were dumbed down. Just bad bad bad. It took me to realize that I was running what amounted to a whole new Opera and not the old one that had served me well.

You can see where the change was. The old Opera, which they appear to still be doing some updates to, stops at 12.x and then the reboot starts at 15 and is up to 19, lol, now. That version is something that again I liken to a Win8 version of Opera. I did not use it long enough, the new version of Opera, to give it any sort of proper review. All I know is that it was bad for me, reeked of some sort of desire to force tablet UI on desktop computers, and dumbed down everything as if I was using some Apple OS/app.
I am not opposed to change but where Opera is going now will not have me as a follower.
