I'm liking it so far. If you aren't crazy about Chrome's UI, it's worth a shot. Hope to see more privacy features, but right now the settings are the same as in Chrome.
And dont forget competition encourages the big browser companies to work together to maintain interoperability, not branching off to 'their software' trying to create a competitive moat or simply because they want to push the world in one direction with monopolistic power. If people have options it stops this typically negative behavior happening.
Your definition of innovation might be different, but both IE and Firefox have gone through major changes for the better ever since chrome entered the scene.
Making browsing and maintaining your own rendering engine is not easy which is why we don't have a lot of competition in the this market.
