How do I get rid of other capacity
God this is so frustrating. I've been having this problem for months on multiple devices and I can't get a straight answer other than "do a restore" which really doesn't fix the problem, it just delays it. I wind up typically with 3-4 GB of Other Capacity and I can't figure out what is causing it. I have latest software on everything (iTunes 10.7, iOS 6, iMAC OS 10.8.2) and new devices (iPad and iPhone 5) and right now my iPad has 2.7 GB AFTER doing a restore. I shouldn't have to do a full restore every couple of weeks. Literally nothing is currently on the device and it shows 2.7 GB of Other. I spent good money to get the 64 GB device, why can't Apple give me useful instruction as to what to do? I have attempted the following based on searches;
Full restore
restore from backup
check and uncheck "Open iTunes when this iPad is connected
Restores should not be something that have to be done almost daily.
