I always have my iphone with me and 90% of the time I carry a cannon SD1000 in one of my pockets. Its not an essential device so there are times it stays in my murse but its something that I like having. Just never know when you want to snap a picture of something or take a short video.

While everyone has an opinion about a camera to carry the best advice I'll give you is simple. If your going to carry it constant make sure its small enough to pocket along with the other 50 things we all carry. Or that you can carry it in a small belt pouch with out being to intrusive to your life and with out looking like a total bat freak because of how much is on your belt.
