I've got an old Pentax Optio S50, let me tell you that unless you go with one of their waterproof ones, Pentax P&S cameras are best left alone. I'm a huge Pentax fan, but even I have to admit that there are way better cameras out there than the Pentax Optio series. I like the Canon P&S OK, I've always been a fan of Sony's P&S cameras. My brother has an 8 MP one that I took a photo of my daughter with, the photo looks great, and I'd put it up against any snapshot of the daughter I've taken with my DSLR.

Just don't get sucked in with the Megapixel thing, with P&S cameras you want to stay between 5 and 8 megapixels, anymore than that and you're going to have image quality problems.

Four movie modes including 30 fps VGA and 60 fps Fast Frame Rate

What is the difference between VGA and Fast Frame Rate? Is one a better quality?
