i've seen this question asked in various ways, and a couple of third party tools (& to small extent Photostream are part solutions) -but-
i planned to completely cut the cord from iPad/iPhone to Mac. iCloud with iTunes Match works very well.
As iTunes is now no longer authoritative for anything on the iOS devices i deleted all the apps from iTunes and manage them on the device.
without iTunes, how to synch pictures from Aperture/iPhoto.
i war back into iTunes, unchecked all the 'Sync' options except Pictures, but that's when iTunes starts to get clever. (i mean stupid)
even though i'd unchecked the sync apps option, iTunes wants to delete the apps on the iOS device. No.. leave them alone! surely that's what unchecked means?
All i can imagine doing at this point is letting iTunes have it's way with my apps, reinstalling them all over the air on the device and letting the pictures sync after the fact.. or next sync, will iTunes attempt to delete the apps AGAIN?
either me or Apple hasn't completely thought this cord cutting business through properly. i hope it's me..
