My experience with DW come almost exclusively from audiobooks so
but i am in the process of buying them.
I just have no real interest in ebooks, and if i get anything of the ereader sort it'd be an ipad or similar that you can do other things on (and would mostly be what i'd use it for, IE web sites, games, etc). though i'll probably get a laptop long before i get a tablet, but thats mainly cause i've been diving deeper and deeper into film editing and such like and it'd be nice to be able to do that at work and home as well. so still no real interest there.
the only exception to that would be Fallout: Equestria which i broke down and started reading, and thats only because as a fanfic its online only. and even then i may end up buying the actual paper novel version of it that is being printed as we speak.
I just prefer to hold the actual book in my hands if i'm reading it myself.
