Image quality: The pics look great
Size: it's small, light and has a streamlined form factor that is easy to slip into a pocket.
Speed: For talking photos, it's pretty fast
In camera image processing: HDR, iSweep, Red Eye
iSweep Panorama: You set it to isweep mode and press the button and move the camera across the scene. It works really well! You can change the sweep rotation left right up and down. There are also settings for image quality.

Battery: It's not amazing and it dies quickly in the cold
Slow Video: The time between when you hit video redord and when it begins recording will turn your hair grey.
Owner's Manual: It's worthless
AVCHD 60p video: It comes into Cinema Tools at 30 FPS. I can't figure out how to overcrank it.

This camera is GREAT! If you are looking for a light durable, waterproof, shockproof camera that takes good snapshots on an SD card. The camera takes really good photos, and the in camera touchup and features are really amazing. The lens is 28 mm equivalent which is way wider than normal P/S cameras. It starts up relatively fast and shoots fast. The isweep panorama feature is awesome. It has in camera HDR which really only produces good images in certain situations (It makes people look orange).

I bought this camera to capture good images and video when I didn't want to haul my 7d. For family trips, around the house, ski/bike/climbing trips, etc. It has been the perfect camera for me for that. The menus and settings are easy enough to use. They're not amazing in terms of user interface and heuristics, but they are ok.

Don't buy this is you need big zoom. It doesn't have it. Other cameras will have better image quality and lenses. As Photo John says, you compromise when you make something more durable. Other cameras, even other Sony cameras, will have better external controls. This one has limited buttons to keep it small and durable.
