opera has always been innovative browser with good features as long back as i can remember(opera on Nokia s60v3 back then). features like great speed dial on mobile n desktop, save for offline, opera turbo mode, syncing bookmarks between desktop n mobile, website overview mode, text reflow.. I have to use addons with other browsers to have these features on chrome or firefox. Opera has a great team. Has poor market share though. They also had good security. Opera wasn't vulnerable to some big ssl bug discovered a couple of years ago. Most other browsers were. They recently switched their rendering engine to webkit though
