Hot on the heels of a ginormous OS X update comes this, the freshest version of the music management software that everyone loves to hate. iTunes 9.1 is live and available to download, bringing with it support for iPad syncing (you know, that little tablet that arrives on Saturday?) as well as the ability to "organize and sync books you've downloaded from iBooks on iPad or added to your iTunes library." The new version also gives users the ability to rename, rearrange, or remove Genius Mixes, but we're fairly sure you stopped caring after hearing the first point. It's weighing in at around 97.3MB (give or take a few KB), so fire up Software Update and get it going... if you dare.
Update: We're hearing that the new version renames "Applications" to just "Apps" and the Genius Mixes / iPhone / iPod touch sync pages have been retooled. Anything else major? Let us know in comments!
