There are those about who would debate even "basically" when RAW vs
jpeg-only is concerned. Not me, though.
For me, the killer is lack of external flash - which I use constantly for
bounce. Makes a helluva difference to the "end result".

Yes, but we're not talking about 'you' are we.

sigghhhhh

OK.
Forget "me".

Objectively there are significant differences.

Happy now?

Yes, but not basic differences, which is what I said.

Does not have a viewfinder. To me it is important. Better to look at
the S5IS. Better than all of them but a little larger.

Best value. Has viewfinder and LCD. Good battery life. Takes all
types 2AA and that is an advantage.

When ever you cram more pixels on to the same size sensor you will get
more noise. The A720 does just fine at ISO 200 or less and can produce
a very good 5x7 cropped and even an 8.5x11 with moderate cropping.
Better at ISO 100.

The resolution of all of the cameras is not really a limiting factor.
Your main enemy is noise.

I chose a Canon S5 IS. I shoot as close to ISO 100 as circumstances
allow with very little noise and get a nice 8.5x11 using a Canon IP4000
printer with OEM ink. I do moderate cropping. The A720 (a friend has
one on my recommendation) is almost as good but the S5 has more features
and a lot longer lense. It also has an articulating LCD that I find
beneficial for macro photography.
