Canon Powershot S40

[Rookies]

Hi Folks

I have been thinking about buying a S40 to replace my Finepix 6800z. I am still unsure if this is the right cam for me. But I do need a new one that have fast shutter speed for sports and motor racing etc. As I want to be able to take picture without blurring.

Can any of you tell me if this is a fine good cam or is there a suggestion for any other cam?

Also what the downside of this cam?
