Don't know what your on about ?? I have iCloud setup, so any documents, i have on my Mac, like Pages, Numbers , iMove, Keynote i can access in the cloud. Others, i have iPhoto on both Mac and iPhone5 and iPad Mini, and again i use the Cloud, Photo Stream.
I also have DropBox set up, so if its on my Mac, i can get them on my iDevices. Or Google Drive and set things to Offline use, if your not near WiFi.
There are a 1000 other Apps that can do this as well. I use Air Sharing, and can use Bonjour by using Safari and putting in the Bonjour Address, i can drop documents from Finder into Safari and i have them on my iPad Mini.
So as you can see, there are a LOT of ways to do this, without iTunes, and what ever you read is a big load of FUD . . HTH
Cheers
