If you have larger documents and with mostly text and pictures, you could try ReadIris. It's an OCR that will electronically read a document and retype it into another application like Word. It even keeps the formatting intact. It's kind of buggy, but it works quite well for basic documents and will convert text that is from pdf, jpg, tiff, etc. Anything it can read. You can also use a scanner to copy a page and it can convert it to a doc you can edit.
Download the free trial and try it. One thing that bugs me about the program is that it's limited to 50 pages, so if you have a larger document you'll have to break it down to 50 pages or less with PDFLab or similar utility, then combine them again in Word. The cost is $129 but after the trial they sent me an e-mail to "upgrade" to the full version for about half price for a limited time.
