Do you always take your DSLR all the time?

No.

On some walks I specifically do want the DSLR.  However, most of the time that I am out I carry a Canon S90.  It does a great job in those situations.  The S90 is usually in a case and then in a bag I carry.

When I go out for a walk and take the S90 it's in my shirt pocket without the case.

Good luck in making your decision.
