One of the most interesting aspects of using a Kindle is how it encourages the reader to switch genres and try out new writing. I am not a fantasy fan, apart from The Lord of the Rings which I've re-read a number of times and Asimov's The Foundation Trilogy which appealed to the mathematician in me, although it's more Sci-Fi than Fantasy.
My son recommended The Game of Thrones series. To be truthful it wasn't my idea of a read and I would not have walked into a shop and bought it. But, hey, I have it on Kindle and am thoroughly enjoying it. When you can test a book by downloading a percentage of it, then decide it isn't for you, it makes it much easier to vary your reading habits. I've often met people at my events who have never read a Rhona MacLeod novel or even a crime book, but once they hear an opening, they're hooked. 'I never thought I would like crime books' is a common phrase. Just like my, 'I'm not into fantasy novels'. The truth is, maybe you never found the right one yet.
Eclectic reading is great. It opens up countless worlds. Anything that makes that easier for the reader (and less expensive) sounds good to me.
