If it's secure, easy to use and browses "the Facebook" I could see giving them to a relative and saivng a fair amount of tech support time. Granted an iPad fills the same nitch but it costs twice as much.
It depends on whether you want a keyboard, too, or not. A keyboard costs extra money for iPad, and it's not a very elegant solution either. I'd much prefer an Asus Transformer if I were to choose a tablet over a Chromebook.
