Canon PowerShot S110 vs S120

Hey, im pretty new to photography itself and want to get a nice device which i can carry with me. To match that, the device shouldnt be too big in size.

I have read about many cameras, and came to the point the Canon PowerShot S-series is the deal I can afford. Especially the S110/S120.

And thats the point i need help. I can get the S110 at currently 220€ (297$), while the S120 starts at 390€ (527$).

I read that the S120 is much faster than the predecessor is.

Which one would you buy? Does the speed justify the price of the S120?

Has anyone experience with a S110? Is it "slow"?
