.....coming from a K3. Self lit screen is great, background is very white compared to the K3, is much faster too. My first ereader was a Sony 505 then I went to the K3. For me at least, the collections are actually a feature. I fired it up, registered it, and there was my stuff! Or at least the ghosts of my books that were still in the cloud but you get gist...Great little device that does all I need it to.
