This could be a common problem for those of us who try to give an iPad to our non-computerized parents who live far away.
For one thing, Apple has no OTA operating system updates, so unless you go visit, they'll never get updated.
For another, without someone there to hold their hand the first few days, iOS can be quite confusing. (E.g. the first time my mother held her finger down on an icon, and they all started jiggling. Unfortunately, that's not an expected result at all.) People who claim iOS is easy for kids and old people, have forgotten that they were there to help out new users at first. Even sliding between homescreens is not an intuitive action to have done on your own, unless you already knew that action existed.
Then there's the lack of Flash support. We would send her emails pointing to Flickr slideshows or some video uploads, and she'd just get blank spots. Drat.
So I put an iOS Flickr app on there she can use, but if the password ever expires, it's a pain to walk her through it again.
Anyway, I loaded her up with pictures as well, and then realized it was going to be nearly impossible to load more on there for her. If someone finds a way to push pics to an iPad's picture album OTA, that would be great.
