Hi all,
I'm a little surprised the name "Pageturner" hasn't been proposed as yet.

So too, "iKnow"
My fondest title for the current crop is "Opus", though for some it mat be less than intuitive. I tend to feel that as time passes, the term "book" or perhaps "reader" will become synonymous with the devices we have today, and their descendants. If said successors have access to the web with information as well as books on demand, perhaps "library" will need to be redefined.
Someone mentioned copyright of "The Book" or similar. Not likely, I think. It was just a few years ago was it not, that Microsoft tried to tie "windows" up as its own word, and failed.
The final say will probably come from the buyers though - something well-known, easy to say, and (in their minds) descriptive. With Kindles being so popular, this might be the go, in a similar manner to teflon from years ago.
We'll know in a few years though.
Cheers,
