Bought both my dad and my father in law ebook readers some 4 months back.
Dad's 86, Father in law is 76, but both took to them like a duck to water.
Had a couple of quick phone calls for minor questions.
I did preload both up pretty nicely so I doubt either one will actually run out of material any time soon.
Long distance tech support can be a bit of a pain, but it can be worth it also.
