Maybe if you're aim is to run some scientific tests, and even then, there are benchmarks already in place, and giga has been willing enough to post the html5test results, and we've discussed those. If you go back and read what I said, I said that the Wp7 browser felt smoother for me, and that I had reference points for the other platforms. Which I do. Why that offended you is anyone's guess, and your suggestion that only folks who have every up to date version of every operating system can comment or post their thoughts is utter bullshit. Cause if that's the case, you shouldn't even be in this fucking thread.
