Although the power button on the T2 is rather flat and hard to press, it doesn't really matter--you generally turn it on by sliding the faceplate or pressing the review button on the back of the camera.
You access most of the T2's options directly via the touch screen; only the review and Scrap Book buttons and zoom switch have dedicated controls. However, the Review and Scrap Book buttons are small and flat, making them quite difficult to press.
Moderate, but still quite visible barrel distortion appears in the T2's wide-angle shots, and there's also some pincushioning at the narrow end. Though not atypical for a snapshot camera, the small zoom range doesn't really warrant it. (Grid lines added in Photoshop.)
