* My Minolta A1 P&S focussed in lower light than the Canon 300D
** at the same ISO setting, a DSLR shoudl have less noise than a P&S
*** But my A1 also does that ... IF you pre-focus and use Manual mode
**** on the 20D certainly, not sure anout the 300 and 350

You may find you carry a DSLR less often than your P&S
Yes, a DSLR that is much smaller, lighter, without a dust problem, a swivel OLED screen, an anti-shake system of course in the camera body, built-in as well as hot shoe flash, WIFI connection to computer and off camera remote TTL flash and designed ease of use in terms of the location of buttons, dials, etc. Needless to say all of this should be at a reasonable price...certainly below several thousand dollars.
