Actually, we bought my 82 year old Mother-in-law an iPad as a gift when she was recovering from surgery. Having never used anything like this before😕, there was a definite learning curve for her, many, many phone calls between she and I for tech support. I really think this book is ideal for Seniors using an IOS device for the first time. She maintains the iPad was 70% responsible for her recovery, the Doctors, only 30%🙂
