I know that this thread is over a year old, but I'm still looking for these same features myself--remember, with e-ink (so ipad is not an option).
Has anyone tried the new Kobo Touch? It looks pretty affordable, but I don't know if the features are really functional. I understand that the new Nook Touch is e-ink and allows annotation, but only for books purchased through the nook store. I am looking to annotate my own work PDFs in e-ink.
Too bad the irex went under. It looked really interesting. Anyone else have any ideas or insight?
