That was almost historic and will still be long remembered - Perez getting the win was the only thing that could make it even sweeter and that was always going to be unlikely. As is, it was an epic performance from both Sergio & Alonso, we have to assume they'll be teammates in 2013. I honestly think Sergio is a bona-fide genius, I'll be amazed if he isn't Champion sooner or later.
Hamilton seemed a little happier which was nice to see, another tough race after doing all the hard work in the first stint and frankly I don't think his pit crew did him too many favors. Still, two poles and two podiums out of two races leaving him second by 5 points is not a shabby start to the year. He's got all the speed, still looking for better luck.
As for Vettel & Button's incident with the HRT, I think Karthikeyan was pretty blameless in both of those - Jenson seemed to simply run wide with him and Vettel clearly misjudged where the HRT front wing was.
I agree with you Retro, at this rate it's going to be another superb season. I really feel we're in a Golden Age of F1 not seen since the classic years of the glamorous 1960s. Roll on China!
