Re: OCR

You can't legally fool around and somehow extract or cause the engine to work independently of the program.  If you purchase Fine Reader by itself, it is perhaps a tenth or a little more of the price of Kurzweil or Openbook.
 
There are free OCR programs that aren't nearly as good.  Also, I don't know what screen-reader you are using, but JAWS has built-in OCR these days that would do the occasional scanning you want to do.

I guess, my point is:  I don't own either of the ocr packages but have
demos  and copies of both.  I don't feel the need to own either, but an
ocasional scan and read might be useful; even though it may be a bit
less accessible.
