I have just purchased a 2nd iPad 2. Its for my 82 yr old father. He needs it for speech rehabilitation, after a stroke. There is a great speech rehab program for the iPad, that he is very familiar with from his therapy, in which an iPad was provided with this app on it, for him to use. He is now out of that therapy, though we all feel that the iPad and the app will continue to be of great help. The app is almost $200. He has no computer. I am considering setting up his iPad to mirror mine. I don't mind purchasing the app, but do I have to purchase it twice? (one for his, one for mine). I won't use the app, but he will. As I am preparing to set up his iPad, I have the option of setting up "a New iPad" or to restore from a previous backup of mine. If I set his up from a restore of mine, will our ipads be viewed as the same iPad? Are there pros and cons to this? Thanks for any thoughts.
