@piatkow, right! Its very easy for us to think the interfaces we are used to are the most intuitive, but none are easy for someone who is exposed to it for the first time.
A tablet is probably simplest. Get one with a big, high quality screen. I read ebooks on my Android tablet, but other people find Ebook readers with e-ink screens more comfortable. On the other hand an Android tablet can be used to read Kindle books (with the Kindle App) and epub books, and Adobe DRMd books etc.
Also, consider how prone she may be to mess things up - even inadvertently. I found that switching my father (a decade younger than your friend) to Linux reduced the number of support calls I got, and switching him from KDE to Ubuntu Unity was even better. The latter is interesting, because the reason it works for him is exactly the reason geeks Unity: it is inflexible, so he cannot accidentally re-arrange it and then complain of lost icons etc.
