Wow....A self answered question. Doesn't leave much room for discussion.
What about the question doesn't leave much room for discussion? I think there is plenty of room for discussion.
The problem with taking your camera everywhere is that, to do so, you usually have to choose between the convenience of a small, very limited unit (I'm thinking as basic as a cell phone camera or one of the new wafer thin point and shoot cams) or lugging around what may be a heavy, but most certainly will be a relatively bulky slr of some sort.
To have really versatile shooting capability with you at all times is, I think, difficult for most of us. There are many times when my point and shoot (and certainly my cell phone) are simply not up to the job, and, so, I skip photo opportunities because I know I will not be happy with the result.
OTOH, the cell phone that I carry actually has a camera built in that is capable of shooting the sort of pictures I need during the course of my work day, so that I can use those photos and forgo having to carry my more bulky equipment.
Additionally, while I am a product of the film era, having a digital camera (even a cell phone model) with which you can check the results often is a better option than a more capable film camera.
If I am shooting to gather onsite evidence, it is more important to do so confidently than to take a chance on shooting film only to review the shots after the fact and discover that I do not have what I need.
It is absolutely wonderful to be able to whip out my cell phone that is with me 24/7 and grab shots that function for their purpose. These aren't works of art, but, as mentioned before, they serve their purpose and then are destroyed.
I often find myself in situations where I yearn for my full kit. Unfortunately, there is just no way I can carry my stuff with me all the time.
I am an avid cycler (bicycle), and my riding takes me through unbelievably beautiful outdoor scenes, most of which, I cannot capture because all I carry is my cell phone camera. My 35 mm stuff is too heavy, and I am not at all in love with the current crop of point and shoot digitals.
I apologize for being a little long here, but, the above represents my take on carrying/not carrying a camera.
