You know, for me some of greatest attributes of e-readers are:
- Convenient portable library at size of your palm
-
Built in Dictionary at the tip of your finger, so as not to break the flow of reading immersion. (Which in my case is really important, because I am obsessive with vocabulary, I want to savor every nuance and subtleties unfamiliar words that are conveyed in the context)
- The Internets huge wealth of content gratis.
- Annotations, bookmarks and highlights,etc..
That being said, I still do have a few gripes with this technology, as some of the members of this forum have mentioned the inconsistent blackness and ghosting of e-ink is inherent to e-Ink unless you refresh the page of course. Also the lag of tactile feel of paper

But perhaps most important of all, the endless pursuit for the latest and greatest model that consumers such as myself would easily fall prey to.
In hindsight owning all these devices is really redundant for
"me" , since the end goal for myself is to enjoy, learn and get the most of the materials that I read. Well that's just my two cents.
