I’m puzzled by your comments. You may be the super maven regarding film based photography, but quite frankly your dismissive comments make you sound like you know relatively little about the technology of digital photography.
Beyond the quality of the lens, as a rule, the megapixel density of the CCD does make a difference and is absolutely critical to the quality of the picture, with (other things being equal) higher megapixel counts generally yielding crisper pictures with enhanced detail and sharper images. Beginning at around 3 to 4 megapixels and up you can usually get near 35 MM picture quality based on printing out the results on a good high resolution, photo quality printer.
The type of batteries used make a huge difference in the real world usuability of the camera with respect how long they will last in the high stress environment of a power hungry digital camera. These things gobble battery power. Rechargable NIMH batteries are the most cost effective and longest lasting batteries under stress of digital photography although some new titanium and lithium disposable formulations may last longer prior to exhaustion. A fully charged set of NIMH batteries will usually cycle faster and give me more shots than a fresh set of alkalines.
The “8X10” standard the digital crowd is referring to is not a camera format or an 8x10 film glossy, but the size that you can output on a high resolution color printer and still have decent resolution and detail in the picture.
No one disagrees that composition is key to a good picture but pixel density specs are not irrelevant for most people and are very visible with respect to output . You may be analogizing from the film world where a decent 150 35mm brand X will have the same output resolution on film as a 1,500 Nikon and the pics will not look substantially better on the Nikon unless some one knows what they are doing with it. Digital is different. A 6 meg 8x10 printout and a 2 or 3 meg 8x10 printout of the same shot will be visibly different.
