There are two things about my DSLR vs. my compact cameras that still motivate me to go for the weight/bulk:
1) instantaneous operation: push the button, it takes the photo, and is immediately prepared to do it again, indefinitely.
2) excellent behaviour in dim light.
There are lots of other lessor advantages, but for me, those two are the biggies.
What's interesting there, of course, is that #1 is in no real sense an
inherent difference between DSLRs and compacts: there's no reason not to put the DSLR electronics and firmware in a compact, and in fact I bet they
do, just with a bunch of sleep() calls enabled, or a slower main crystal or PLL. In fact, I also wonder how much of #2 is inherent: the sensor is bigger (but it also has more pixels), and the lens is bigger (and thus probably brighter), but do those make up the whole difference in low-light performance, or is part of that also artificial product differentiation?
