You most certainly already knew that Palm’s newly announced OS, WebOS, was codenamed Nova prior to launch. If you didn’t then we invite you to stop by slightly more often and up your gadget cred a bit. What you probably didn’t know however, was that Palm’s knight in shining armor was codenamed Castle. How apropos. The fellas at Palm must have been so exhausted from making sure everything Pre-related happened on time that they forgot to update the copy in an automatically generated confirmation email. You know, kind of like how the BlackBerry Storm is still referred to as the BlackBerry Thunder in some OS files to this day. It’s okay Palm, you did a hell of a job keeping the wraps on your recent announcements and it’s safe to say both the Pre and WebOS are pretty widely acclaimed at this point. Get some rest and then see if you can’t get around to cleaning that up.
