It is different from the computer to me for several reasons. 1) reading in the car–it is not safe to have a laptop open in one’s lap in a moving vehicle; the kindle OTOH is so lightweight and small and much safer 2). I think it is also much easier on one’s eyes and it does read like a book (just not pages to turn but you do push the page-turn button).
I was hesitant too, but I have so many more books than I could possibly have w/out the kindle. I have the entire GA Henty collection and it was $1 on amazon. I have many of the Burgess books, which my 9YO son reads again and again.
We have multiple children who have multiple dr. appts. at our local Children’s hospital, and the kindle is a great way to pass the time. Only trouble is only one person can use at a time. Actually that is not true. Two of our sons will read together, one looking over the other’s shoulder.
I find the kindle very user-friendly and very basic which is what we wanted. I am sure the ipad is great (I am an admitted MAC fan; have 3 of their computers and an iPhone as well and have used the computers for years), but I think the iPad has many more features.
If I were getting a kindle, I would get the basic one.
Keep in mind that your local library probably has an e-reader lending program as well. Ours does and they only work on a kindle or a nook. Not sure why but that is how they work. I have read many books that way as well, though we still bring home many paper books from the library.
Mileage varies but this has been ours.
