> How would Etaco JetBook Color match up here?
Well, not at all, as I am looking for a black-and-white e-ink reader with high resolution. But thank you for mentioning it, I am aware of that one as well.
Right now, I am heavily leaning towards the M92, mainly for the fact that it offers 2-column-reading, which I find incredibly useful on the iPad Kindle application.
To be honest, it always baffels me why Amazon would give the iPad Kindle application better features than their own Kindle readers.
