To clarify (I wrote ambivalently): not ABBY Fine Reader is for Windows
only and *extremely* expensive but "Djvu Document Express"


It looks like they finally updated ABBYY FineReader® Express Edition for Mac

ReadIris is also pretty good while Omnipage went into obliviation


It looks like Fujitsu ScanSnap S1500M does not have a platen glass but
only ADF. Those are very fast but expensive. I achieved very good
results with  Canon Pixma MX310 ($100) but I never use it for
printing, copying or receiving faxes. Sure it is not as fast
