I have a 64 GB iPad 3 running the last version of iOS 5. It is pretty much full of apps, all of which were saved to my iTunes folder when I synced it last. However I now never sync my iPad with my Mac and iTunes, yet I have nearly 64 GB of apps backed up there in iTunes. It is a lot of wasted HD space it seems. Now that the iPad's apps are backed up in iCloud, is there any need for me to keep all those apps in iTunes on my mac? Can I just go ahead and delete them? I am not sure if there is some reason for keeping them. It would save some much needed space on my MB.
