I have over 100 iOS apps in three different devices, an iPod running running iOS 4.2, and an iPhone and iPad on iOS 5. As much as possible, I always sync all devices to my laptop so that they all have the latest updates. I know that since iOS 5, apps and songs purchased from iTunes on one device will automatically sync to other devices. That said I still find that I have sync for other reasons, to transfer photos to iPhoto and sync a large number of podcasts I listen to. And perhaps, most importantly, I’ve sync to charge my device. One issue, definitely first world problem, I have with having multiple iOS devices is managing all the apps in the different devices. If I delete on app from the iPad, it doesn’t delete it from the iPhone. If I delete it from the iTunes on my laptop and I sync with a device that contains that app, it will copy it back to iTunes.
Another big issue is that you have to configure your app pages and folders on each device. If you spend an hour organizing your apps into folders and pages in one device you have to re-do it all over again on the second device. What ends up happening is that you’ll have two devices with the same apps in different pages and folders.
What I am missing from my mobile experience is the ability to sync, not only the apps and content of apps, but the meta-data about how I organize apps between iOS devices. I want to have the choice to clone how one iOS device organizes and layouts the apps to other devices. I would also like the ability to have different app layout settings, such as have the iOS device automatically put applications into folders based on the app category or my usage of the app. And of course, I would like to have a way to delete an app from one device and have it disappear from all other devices.
