The main reason why I kept my PSP is to use it as a rear view mirror for the F1 game.. but since the functionality did not come out for the US version, I am not pleased.

I am enjoying the PS3 version.  I have two profiles going on.  One is racing in medium setting with aids off, while the other is on hard settings with some aids on.  I find myself having more difficulty in pulling out consistent lap times when the sun is glaring in my eyes, unlike the PS2 or PSP versions of the game.
