Mine got a hairline crack in the chassis next to the charging port, but the magnetic charger didn't have the same issue (obviously). There were plenty of issues with the Pre and immediate followups didn't do enough to solve them. That said, it was probably the last really "interesting" phone design I owned.
I knew somebody with a Pre and he had to have it replaced two or three times because the charging mechanism kept breaking. It’s fairly common that somebody else will do something “first” but Apple will wait until the technology is mature enough to be reliable.
