@ehBeth,
We have an iPod so we've got that covered. Ours only has a tiny screen though so he couldn't read along.
I too can't even imagine what might be available in the near future.
My neighbor's first Kindle is now a paper weight. I think she's on her third generation now.
My mom said she just clicks on the book she wants on the Amazon site and it shows up on her Kindle in just a few minutes, without having to plug anything into anything. That sounds pretty wonderful to me since the nearest bookstore is at the mall and I absolutely hate going to the mall.
