Since Apple is taking the stance of needing no cord and what not with iCloud coming. I noticed or read that at least with music once you purchase it, it was always be available for redownload later and songs will not just mysteriously go missing etc. Does this apply to apps as well? I know in the past some apps have been removed by devs from the app store and the only way to use was to keep it or restore it from iTunes local library. Going forward will this purchase history of apps store everything we purchase like music forever? Or do we continue saving everything locally and hope nothing just goes away? Thanks for anyone who can shed light here!
