You know that HP logo on the Pre3's back cover? The silver rectangle in the loop of the capital P is partial to falling off. Just in case you want to pre-emptively pry it out and glue it more solidly. My wife lost hers a few few weeks after we got her Euro Pre3 and my AT&T just shed its own a few days ago.
It looks kind of sad. I must mention that one thing I like about the Pres which is rarely mentioned is how the finish stands up to wear and tear. There's no paint to wear away and chip off; my mother-in-law has the original Droid and it's in SAD condition.
