ok, here is what I have learned in my recent research.
after my 2 y/o tossed my nikon 8700 into the ocean this summer, i found myself looking for a new camera. I wound up getting two, because I wanted an slr, but everday carry was out of the question with it, so i got a compact point and shoot also. after extensive research, i purchased the pentax optio s5z,
HERE from b&h, for $264, plus tax. added 2 one gig SD cards, and three extra batteries, and tiny belt case and total came to $550.
Reasons i chose this one, and I looked at them ALL, in person, is as follows.
smallest overall package, just a hair bigger than my cell phone
5 mp, with 3x optical zoom
2.5 inch screen
great lens
yada yada yada
but the ONE DECIDING FACTOR was .01sec shutter lag. best in class by a margin so wide that it became a no brainer.
anyone who has ever used a P&S digital know how frustrating shutter lag is. It is non-existant with this little gem, and I love it. The quality of pics is great, and it is one of the most intuitive little guys I have ever used.
check it out, you will be amazed by this one.

no optical viewfinder, but more than compensated for by the screen, big, bright, and sharp.
also, I have been a nikon guy for 25 years, and it was hard for me to consider a pentax just because, but it made the comparable nikon look huge by comparison, even though the specs were almost identical otherwise EXCEPT shutter lag
