Woo hoo! I shouted at Raikkonen all the way around La Source that first time, and after the safety car he nearly ran over Fisichella at the top of Eau Rouge while going past.
After that, some steady driving, combined with Fisichella's tactical inability to take any real chances (lets face it, Fisichella was under orders to bring that car home in the points no excuses) solidified the win.
That said, the total absence of Brawn and McLaren cars at the sharp end of the grid, plus some bad luck for the Red Bulls also helped; Vettel demonstrated the ability to reel in the BMW, Force India, and Ferrari ahead of him; however it's questionable as to if he would have been able to do anything about any of them had he actually caught them.
Those of us who remember our history know that one race does not mean that a team has permanently fallen behind or sprung ahead. I remember the March/Layton House team struggling to qualify in Mexico, and two weeks later in France running second and third. Force India has to show that they can repeat this kind of pace before we'll decide that they have legitimately improved.
Similarly we can enjoy the improvement in BMW form, something which should go a long way towards securing the team's future as a viable enterprise. But in the absence of the championship contenders, we can't really draw any conclusions.
But for Ferrari fans, it was a good day, one we'd doubted that we would see given the lack of pace at the beginning of the season.
