After purchasing multiple android tablets, I went with iPad finally a couple years back. Why? It just worked. All the time. I've had very few hiccups with it. Apple reviews every single app that goes on their (unless you jailbreak it), so you're almost ensured having quality. Android, however, is not that way. If you do decide to go with Android, do not go cheap. Go with a Samsung model (there's several to choose from). Samsung seems to be among the best out there among Android tablets.
Oh, yeah... After multiple issues with my wife's Android, I took her to the store to "try out" an iPad mini for just a few minutes. Those few minutes paid off. She was sold and hasn't had any issues whatsoever with it, unlike the Android, where I was constantly "fixing" it for her.
