You can easily be competitive on both, only on laptop you can see a little bit more data from past races (tyre wear, fuel), and watch ads, but there isn't a big difference.

Wrong Rik, you can see the same info on past races. It just takes learning the system.
Now during the race, you really can't get as much info because you are limited by screen space, but the 2 systems are meant to be nearly identical.
Sorry, I don't play that much on Mobile phone so I don't remember that that good, most of the times I don't need to see the tire wear and such too. But I though you can't see everything.......
