I didn't think about that. Without knowing a lot about javascript (I'm not a dev, I just dabble in programming every now and then, but my javascript knowledge is largely theoretical), isn't the engine used in the browser playing an important role in performance? WRT to the javascript performance, android's biggest breakthrough was a software one- getting the v8 engine in 2.0. Even the Hero's performance improved significantly when I stuck 2.0 on it. I also recall playing with a Desire, clocked at 1 ghz (different architecture than the N9's TI CPU, granted) and browser performance was very, very good even in heavy websites. I'm optimistic that with a good engine, the N9's performance will be good enough.
