With the iPad comes new iTunes. MacRumors hears that 9.1 will have a minor overhaul, organised around books, and smarter, more customisable Genius mixes.
The Audiobooks section will become simply Books, which'll show all of the book stuff you've got in iTunes, sorted by compatible device (iPad vs iPhone). And of course the device sync screen will change accordingly, so you can manage your book content, along with minor tweaks like moving the "check for updates" button.
In terms of new powers, Genius mixes will be more customisable, and you'll be able to use them as sources for iTunes DJ. Also, other devices are supposedly picking up a perk from the iPod shuffle, which is auto-converting tracks to 128kbps AAC when you sync, saving space on the device but leaving your bigger source files in iTunes.
You know what I'd really like too? A leaner, meaner iTunes. Maybe that'll come with 10.0 and cloud streaming. One can pray. [MacRumors]
