I would agree with this. I find it hard to frame a photo in bright light without a viewfinder. The other advantage of the viewfinder is that it takes less power than using the display, if you use your camera a lot, it conserves the power.
I also like using disposable batteries, because if my camera runs out of power I can change batteries and won't miss any shots
As for cameras that meet your criteria, I would look at Nikon AW 110 or 120, Olympus Tough cameras. typically the waterproof, shockproof cameras have an internal zoom lens. I don't know about usb charging. And not too expensive in comparison to my digital SLR camera or the Nikon AW1 which is on my wish list.

At least if you plan to shoot outside and want your photos to be well-composed and/or in focus. In my experience, most LCDs are difficult or impossible to see outdoors. It's one of the reasons I avoid using a cellphone or many newer point-and-shoots as my primary camera.
