If some (or most) DSLR owners use it that way it does not
mean they are stupid, or materialistic - it means they bought a
camera that takes better pictures than a P&S, and they use it to
take those pictures.
My materialistic comment earlier was by no means targeted towards all green box shooters. I have plenty of friends and family who only shoot in auto mode who aren't materialistic by any means. Some may be misguided, but definitely not materialistic.
I think you touched on an another interesting topic when you mentioned how "[a DSLR] takes better pictures than a P&S". Is that actually true?
I would argue that green box shooters are less likely to post process or use custom parameters than someone who shoots in one of the creative modes.
So what are the advantages of a DSLR for a green box/kit lens/no pp shooter?
Better pictures?
There are at least 2 or 3 posts a week here stating how so and so's [insert name of P&S here] shoots [sharper/more saturated/brighter] pictures than his/her [insert name of DSLR here]. The typical response given here explains how DSLRs by default use less in-camera processing to give you more flexibility to post process and that you typically don't get the true benefits of the camera until you post process your photos.
Low light performance?
In green box mode, if I remember correctly, you're limited to ISO 400 and a minimum shutter speed of 1/60. In most low light situations, your on-board flash will be used. The on-board flash, when used as a primary light source, yields similar pictures to your typical blownout P&S photos.
Aperture - DOF?
Sure those narrow DOF shots look great on a DSLR, but in green box mode you don't have control over it. I guess, you can get lucky every now and then if your camera decides to use a wide aperture.
Responsiveness?
Yes, DSLRs are very responsive which makes them great for moving targets (children), but most advanced P&S cameras have similar responsiveness nowadays.
Megapixels?
Both DSLRs and point and shoots are in similar resolution ranges nowadays.
Picture Quality and Noise?
Yes, a DSLR has a clear advantage over a P&S with picture quailty and noise. But in your typical 4x6 photo, those differences are harder to see.
So, what advantage does a have a DSLR have over a P&S for photographer who only shoots in auto mode, doesn't do any post processing, and doesn't plan on swapping lenses? Other than future growth potential, I can't think of any. Perhaps someone here can mention what I missed.
I would argue that it is ultimately the photographer behind the camera that takes the better photos.
I apologize ahead of time, if I sound cocky. I don't mean to be. Personally, I agree with one of the previous poster's "to each his/her own" attitude.
I've said this before - I'd rather look at a well composed picture
with technical flaws than a technically perfect but boring shot. I
have seen many many of the latter posted here by people with
thousands of dollars invested in gear.
It is always a bad idea to judge everyone else by your own
arbitrary standards.
I totally agree.
