Chris Foresman with the scoop from Ars:
At the same time, however, authoring standards-compliant e-books (despite some promises to the contrary) is not as simple as running a Word document of a manuscript through a filter. The current state of software tools continues to frustrate authors and publishers alike, with several authors telling Ars that they wish Apple or some other vendor would make a simple app that makes the process as easy as creating a song in GarageBand.
Frustration and user needs leads to change.
Update:
Fortune is claiming that the Ars information is “seriously overhyped” and is not likely on the horizon.
