Over the last 14 years of travelling for work and making contacts, I have picked up a huge amount of bookmarks. Depending on the job, country and company I work for/with, I have all the information at my finger-tips, so-to-speak, through my bookmarks; some 9000 of them. To find out that I can't import them into Opera, I'm using version 23.0, nor do I have access to them via xmarks, is a massive let down. Opera is obviously a browser to be used in school, universities and internet cafes where saving bookmarks is not at all important.
I might use it for my tablet or smartphone but not for work.
