Got a hairline scratch on the touch screen (not over the display, on a black part of the front of the device); still not sure how, but anyway -- found that high-quality auto paste wax made it less noticeable.

Also bought a couple of Clarivue clear protectors and installed one yesterday. Fit is a little loose (1-1.5mm of room all around) and 2nd of the 2 removable layers (you take these off during installation) came off before I had the protector fully positioned, but adherence is excellent with no bubbles and overall product quality is excellent. You can feel during the overlay step that it's a really tough little layer of plastic. No visual distortion, no loss of sensitivity noticed. 2 for $10 on their site plus you get a coupon for your next purchase.
