iPad Ad Reveals Book Prices, My Documents & Possibly Camera?

Apple’s iPad ad which aired during the Oscars, seemed to stir up lots of attention. AppleInsider notices what might be pricing of the new iBook Store:

The commercial showed Sen. Edward Kennedy’s “True Compass: A Memoir” for $14.99, the novel “I, Alex Cross” by James Patterson for $12.99, and “Three Cups of Tea: One Man’s Journey to Change the World… One Child at a Time” by Greg Mortenson and David Oliver Relin for $7.99.

For comparison, “True Compass” currently sells for $19.25 for the Amazon Kindle, “I, Alex Cross” costs $9.99, and “Three Cups of Tea” costs $7.19.

TUAW notices a New York Times Best Seller section button at the bottom of the iBook Store:

9to5Mac notices ”My Documents” button located in the upper left corner of the iWorks application. What’s weird, ”My Documents” is used under Windows and in OS X, it’s Documents.

Finally, 9to5Mac also notices possibly a camera is shown 3 seconds in, or maybe it’s a ambient light sensor?

What’s your opinion on the following images? Do you think the iPad will have a camera?
