I recently had a conversation with a colleague about something I had read a while back. The concept of the ready or useful camera. I have my DSLR, I have a P&S. But both of those cameras require me to remember to bring them with. They are a little bulky (or in the case of the DSLR very bulky) to simply carry on me.
However there is a camera that is by my side no matter where I go. It is the 3 MP camera that is integrated into my smart phone. I'm making myself a promise to use it more and more. Seeing a great shot present itself is nothing if you don't have a useful or ready camera at your side. And with my Blackberry, there is always one there waiting to be used.
