Opera thinks the current state of web browsers kind of sucks, and they’re pretty much right. Instead of just complaining, however, they developed a now browser concept where they can experiment with different interface ideas. They’re calling the browser Opera Neon, and it’s available for Mac and Windows users to try out. Neon does away with familiar elements like tabs in favor of bubbles that float at the edge of your display. Performance is a little slow right now, but it’s a concept platform and not a finished product. You can download Neon for free at the Opera website.
