My biggest concern with "Kindle" is you can only use ebooks that are bought from Amazon. I believe all of the others can use a wide range of formats (i.e. e-pub)
For example a person can buy a library card for ~ $12 a year. Rent e-books all the time (library rents e-books for 3 weeks at a time).
Kindle would not be compatible with Ebooks from the library.
