Just found out about this as well
Got confirmation from Apple as well that this is how it is suppose to function.
They need to add a button to see all apps on iPhone and download. I had SOOOO many apps that I have purchased/free since the iPhone 4, and I have 140 apps on my iPhone. I don't have the time to sit and go through all of them to get the ones I need.
camera roll fiasco all over again, yup. watch apple revert or fix this in 9.x, well they better.
(+)u saved me some disk space from being able to delete all the apps in itunes library, yay..
(-)u made it confusing as ****
(-)now i have to manually manage apps on my phone (as expected), but now on itunes too? garbage. if u download an app for the first time on ur device, delete it, then take it again, itunes wont download it the second time even if u delete it from itunes. smart, very. (not really)
(-)depending on internet now (apparently) to redownload all those apps when u restore from backup, way to extend the restore time by over 3x for nothing, even if u got "fast internet", & what happens if an app is pulled from the store? oh i have to manually dig through my huge app install history to pick it out
(-)um appdata..? still confused as **** about that
(-)so apple removed a feature, yet left it in itunes showing no sign of removing it, its that hard to remove the transfer purchases option.?
(-)why is there no option to "download all apps installed on this idevice" to itunes from the store?
(-)live in the cloud? that way still downloads gigabytes worth of apps, slowly (compared to syncing speed)
1 plus, endless minuses, great. literially as ticked as i was about camera roll before, i am about this. apps are "thinned", okay um fine..? still whats so HARD about moving those apps from ur device to damn itunes? i only got 1 iphone, i dont care how "thinned" they are for iphone only, put them on itunes anyway..whole thing makes zero sense. itunes should be smart enough anyway when restoring a backup or syncing, to "thin" the apps appropriate for the device its syncing to, problem solved.
