The SD750 has an attractive, slim profile, and the camera fits comfortably even in a front pants pocket. The small on/off button can be a little difficult to press, though, since it sits flush with the top of the camera.
The shiny, black back looks pretty, but it and the LCD show fingerprints and dirt pretty seriously. Overall, though, the camera is well designed. The Touch Control Dial, which provides quick access to frequently used shooting settings, features a raised lip around the edge which makes it easy to feel without looking. Plus, you can set the camera to bring up a virtual replica of the dial on the LCD--handy for when you can't see the controls.
Canon typically applies less sharpening to photos then other consumer camera manufacturers, which minimizes the crunchy look we often see from oversharpened images. The trade-off, however, are slightly soft-looking details, as with these leaves. However, the camera generally renders very accurate colors and excellent exposures.
