I want a Digital "Take it everywhere" Camera. I'm pointing towards the Canon Ixus II. And is stylish. What are the differences between the IIs? Also I think the 2x optical zoom is very short... The option is the Ixus 430 but is more expensive, a little bigger and heavier. What do you think? Is the Ixus II a good quality compact camera? I've seem the Pentax Optio S and S4 but I prefer the Ixus models.
