I just bought one. I want the form factor, not for reading long form ebooks.
Out the door with a case and screen covers it was about $120 USD. We shall see how it all goes.
Looks cool, but if I have to copy Epubs to it, then that severely limits it's use for me with library books.
Maybe one day they'll have a version with Android on it.
calibre plus plugins solves for this
Actually seems like a really cool product, not sure if it would be that useful for any serious reading due to the small size but probably useful for displaying a calendar and other widgets.
