... All!!
I'm a pretty new ebook reader (human ahahah!), with an even newer e-reader Kobo Glo.
I'm not so "new" as paper's book reader, because I have been readince since when I started being able to understand more than 3 words in a sentence (more or less when I was 5 years old...).
I'm a sf fan, but I also appreciate good thrillers, action and historical books (oh, I forgot comics: Tex Willer, Batman and his world, Wolverine, the rest of superheroes, Corto Maltese, Beetle Bailey, B.C...)
