Why are all my iTunes apps required to be downloaded onto my HD in iTunes? Isn't it good enough that it's all stored w/purchase info etc on the cloud? iTunes also keeps trying to update my apps but shouldn't the most recent update already be present on iCloud? There always seems to be a huge queue of apps wanting to be downloaded and updated but updates fail because of time outs. Purchased items on iPhone want to get transferred to iTunes and when I click yes and do it, it fails for some reason. Streaming from iCloud from the iPhone is actually more reliable than playing iTunes on the main computer as sometimes, playback just stops... Anyone know of any ideas why this is all happening? Storage is on a Drobo FS NAS.
