The point of purchased is to let you retrieve purchases. The point of purchased history on the device is to let you retrieve it on the fly. The point of syncing purchases to the pc is so you ALWAYS have them. I personally don't need to flip through 900 apps in my history on the phone. The apps that I use are already installed from syncing or downloading. Again, hide the non useful, unused apps from your history and experience no crashes, or leave them there and continue complaining about AppStore crashing. Makes no difference to me, I've solved the problem and felt I would share. It's here for those people who would rather a fix than to sit and complain : )
