We have had a Sony E-Reader for a couple of years now. I just got the Nook. On our 27 Ft boat an ereader is required.
We have a bit over 4,000 E-Books now. So, when we are not reading a good paperback from the lending library, we are still well stocked!
We were hating trying to read from a computer screen, but these readers make it much easier!
