Alonso proves that consistency is still key in F1, consistenly finishing near the front and just finishing races, remember, Massa led after Maylasia due to being consistenly up there early on, and I think it was in 07 or 08, Hamilton was leading after a few races, and he hadn't even won a race. Consistent pace, rather than wins gets you the F1 title, you can even look back to the Schumacher era with the likes of Montoya. He had immense pace, and so did the BMW powered Williams, but the Ferrari Schumacher combo was more consistent with it's results, and thats what made Montoya not win the title. He was just a fast (even faster and I'll admit that, and I'm a mega Schumacher fan) but things like his car, and some of his races just didn't fall into place, unlike the Schumacher Ferrari results in the dominace from 2000 - 2004.
For the points system, I think its the best I've seen it, because, if you have a bad race due to mechanichal gremlins (Korea for Vettel), with a win, you can be right back up there, and that just makes it more exciting for us. Now, he wouldn't have been up there if it wasn't for his consistently great pace. I think, F1 ought to give out points for pole posisition and fastest lap, as it adds another bit of spice, especially for the midfield teams. Imagine one of their drivers are out of posistion no where near the points, the team might bring him in 5 laps from the end, give him clean air, on the faster tyres, to give the team one extra point. Williams are now just one point ahead of Force India, so it all adds up.
For tie-breakers, counting wins isn't the best thing for judging a drivers season on, but there isn't anything else they can do really.
So to conclude, the F1 points system (and may it forever be a points system, no silly medals system, apply that to the Schumacher era, would be almost pointless for Ferrari to turn up for the second half of the year some seasons) is good, it rewards consistently, but gives drivers the big incentment that, "yes, I've just had a bad race, but a win gets me right back up there" example, Vettel at Interlagos. But maybe add some token points for fastest lap and poles, would make things interesting and would force a team like Mclaren to take a long hard look at their Quali pace.
