did you look at the Entourage eDGe? that's an Ereader and a LCD. i've got one and i'm serious hooked to it. one of the things is reading a PDF and searching at the same time internet. also making annotations etc etc. a very multi functional device. the only disadvantage is his weight. it's not the device to take with you on vacation to the carribic. for that we take our IREX DR800SG.
check it out, I would say....
