The commercial shows Ted Kennedy’s memoir True Compass priced at $14.95—which 9 to 5 Mac points out is cheaper than the $23 hardcover, but also the $19.95 Kindle version. Of course, there is no guarantee that this pricing is valid; it could simply be a mock-up for the commercial.
Also, iWork involves the use of a “My Documents” folder. I’m not sure whether this is just an iWork thing, or is the promised “sandbox” to be used for USB syncing third-party applications as well. Either way, as 9 to 5 Mac notes, the nomenclature is interesting.
