Just out of curiosity, I have just tried it, and it doesn't seem half as 'new user friendly' as Firefox or Mozilla. The cookie handling isn't as good as FF or Moz, in that there doesn't seem to be a way to save certain cookies, while deleting the rest, therefore, I would have to re-log in to Pals each time I visited, which wouldn't be that much of a hardship, but an unnecessary annoyance none the less. I also tried visiting my online bank, and for some reason, it kept telling me my log in details were incorrect, but I am 100% certain they were right, and tried it three times. I then went back to Moz, and logged in successfully, with exactly the same log in details as I was using with Opera.
I also tried out the Mail client, but found it over cluttered and too complicated for a 'first timer'. I wanted to get it to import my mail accounts from Moz Mail, and after 15 minutes, I had still only managed to import one account, including mail, which I then had trouble finding. I have to admit, I lost patience with it at that point, so maybe I could have customised it to my preferences, but quite frankly, I couldn't be arsed, when there doesn't seem to be any benefits of using Opera over Mozilla or Firefox.
