...year compared to last year? compared with last year where he almost won the formula 1 championship against Fernando Alonzo, this year, Kimi and Mclaren seems to be missing in the picture

Simply the car is not good enough.

McLaren seem to be struggling because of design issues and serious performance flaws, that they might owe to the Mercedes FO 108 V8 engine. Anyway, sometimes the driver makes all the difference. Remember Raikkonen's drives from last on the grid up to the podium.:P
This year, their place in the fight for the titles has been taken by the Maranello morons.
Go Renault!!!! And possibly McLaren, because that's where Alonso is going from 2007.

Reliably is the word Period. Mclaren is slower car. I Doubt they will impove next year. I belive its a Bad move for Alonso to move to Mclaren. Raikonnen would kick butt in a Ferrari or a Renault
