Palm WebOS Dev Books?

Yes, day three of posts about Palm WebOS and yet another question.

Yesterday Robert Scoble asked me for some info to send the Palm Pre, so I am guessing I am most likely going to see it tomorrow when I get back into Sacramento. (I bounce back and forth from SoCal to NorCal every few months it seems.)

When reading about the Palm Developer event from a few days ago, some of the information that was coming out of the event was that the attendees were given a Palm Pre, a Palm Touchstone and a O’Reilly Palm WebOS Developer book.

When I checked Amazon, the only O’Reilly related title that I could find was “Palm WebOS” and it wasn’t highly rated on Amazon. While I hope that it made it into the box, I am also looking for additional resources for Palm WebOS development besides that book, and the Palm Dev site.

Anyone have any other sites, books, articles, etc. that they could suggest to visit/read to get up to speed on Palm WebOS development?

Thank you for your feedback!
