I think its up to Opera developers path it wants to choose. But I will just say.
I have been using Opera for long time, almost a decade. And other options were there at that time too. I mean Firefox, IE and Safari.
But what made Opera unique was it included notes, manageable bookmarks (I mean u can make folder inside folder), feeds, torrent support and opera sync. Than they added Speed dial. So it made user have all features at one place.
Now what happens is they have a browser just like Chrome without all these features. Plus Chrome has addition support for Google account and apps on homepage.
OPERA IS LOSING ITS UNIQUENESS. By being similar to other browsers you will not get much.
Anyway Opera 24 and 25 could not even import html file of my bookmarks exported from Opera 12. Guess what Chrome did. It synced my html file. Now all bookmarks are saved on chrome
And feeds are there on 'feedly'. and notes on 'evernote'.
Worst thing is there is no sync on Opera mobile and Opera mini for android either. They just open link to opera sync page.
Now Chrome can sync via google account to mobile and desktop and I don't have to remember Opera ID and password too.
Guess who lost?
I still love opera, my first browser love.
Yes of course I can use Opera 12. I don't care about few millisecond difference made by browsers. But guess who is missing important security updates which are very important nowadays in era of Social media and Internet banking.
