I have owned a variety of reading devices both e-readers and tablets. I would list them all but it would just be an embarassment to admit and make it even more difficult to attempt to answer my wife's constant question, " And why do feel you need another reading device??"
Well based on an experience with e-readers that is both difficult to rationalize or to afford, I can simply answer your question by saying, yes. Based on my experience, I would say the perfect reading experience would be a Kobo Touch with an internal light.
And, that is why, I will be buying a Kobo Glow ..as soon as I figure out how to answer her question.
Which unfortunately, may take a awhile
