The iTunes 9.1 update is now available for download. Based on the change log, it looks like it's bringing the changes we've been hearing about:

• Sync with iPad to enjoy your favorite music, movies, TV shows, books and more on the go
• Organize and sync books you've downloaded from iBooks on iPad or added to your iTunes library
• Rename, rearrange, or remove Genius Mixes

Still doesn't look like we're getting our wish for a leaner, meaner iTunes granted, but at least it'll play nice with our iPads this Saturday. [CrunchGear]
