Yes, Casino Royale was a reboot.

As you've stated before (I think in the Star Trek thread), iSm, the James Bond series kept changing - with new actors playing Bond (and M, and Moneypenny, and Felix...) with the occasional reference to a previous adventure. While the movies were all basically standalone, there was a feeling of a series (albeit a sloppy one, I'll admit). We were always meeting Bond in the middle of his career - he always already had a reputation. The problem was, he was perpetually the same age, while the world around him changed. Was he a Cold War spy? An anti-terrorist? Yes, depending on when the movie was made.

With Casino Royale, an attempt was made to start the series again. He's a new agent, just achieving his "Double-0" status. The next movie, Quantum of Solace (without making a value judgement) picked up the specific thread from the CR and continued the story.

As far as Singer's Superman is concerned, I'd agree that it's a tenuous reboot, as it's more a sequel to Superman II. While it erased the timeline after the second Reeve movie, it didn't restart the story... interesting point.
