The 90 degree viewfinder was a good idea, but I don't wanna lean
towards the camera to see what's going on.

I think I am going to get a Canon G6 with its swivel LCD. I will use
the LCD as the preview window.

Since the s3 IS and other canon and other p&s have a swivel screen, this
would seem to solve most of the op's problems. I don't know of a remote
release. Delayed release might do the trick.
I would be interested in knowing what they 'crippled', although I would
only move to that series if my present camera had to be replaced, by
which time I wouldn't find a new s3 anyway.

The G6 is an excellent little camera.
1. Can you find it new, G7 is latest and for reasons known only to the
wizards at canon they removed the swivel screen.
2. Canon have some other excellent models that might fill your needs at
lower cost although the lens quality on the G6 is very good and might be
hard to match.
Good luck,

The G6 also has A/V out, so it could be used with a remote screen on a
device with composite video-in.

I'd definitely get the G6 over the G7 if a G6 can be found. I think
Canon decontented the G7 to try to keep people from buying it over a D-SLR.
