Cosmetically, the WB2000 isn't too much different from the older WB1000. Both have dark black bodies, but the WB2000 has abandoned the durable aluminum body and leather grip pad found on the WB1000 in favor of a plastic body and plastic grip. Unfortunately, this change to plastic does make it feel a little cheaper.
Up front, the large 24mm Schneider Kreuznach lens stares back at you. This lens has a 5x optical zoom, and a digital zoom of up to 4x. Samsung has also relocated the flash to the left side of the front instead of the right side where it was on the WB1000. The little plastic grip here seems to be mostly esthetic. I didn't find that this grip did anything to help me hold the camera since that part of the body is already formed out slightly to help with grip.
Up top, the similarities are also very subtle between the two models. The same battery and memory gauge design is used here, which is great to see. This gauge design is very unique and very easy to read on the fly. Also up top is the mode dial, shutter button and power button. Around the shutter button of the WB2000 is a new zoom toggle - similar to how zooming is done on a lot of other compact cameras. The WB1000 used a zoom paddle on the back of the camera, which I never quite got used to since all my other point and shoots have had the toggle around the shutter button like the WB2000.
There's quite a number of modes available on the WB series, which makes it very versatile for it's compact size. Alongside full auto mode, you've also got HD video mode, scenery mode, dual IS mode, full manual, shutter priority, aperture priority and program. The WB2000 isn't too far off from my DSLR when it comes to available shooting modes!
