Am very surprised there's no forum for GoodReader, given that it is so popular.
Anyway, I'm even more surprised that nobody is using FineReader (yeah, it's expensive) with GoodReader. A typical 300-page book without FineReader's MRC compression is about 22MB (150dpi, readable). That same book with MRC compression is 7MB! Imagine carrying 100 such books (300,00 pages in total) on your iPad, and it'll all come up to only 700MB!
Unfortunately, GoodReader left out a key tool that the basic humble Acrobat Adobe Reader has by default: the ability to read MRC compressed PDFs! It reads them, but the text quality is garbled, totally unreadable (unless you're scanning picture books without text at all).
I've written GoodReader's developer about this. (Saturday now). Let's see if he'll respond to this.
Anyway, for anyone intending to use the marvelous FineReader (yes, it is terribly good) with the popular GoodReader... DON'T!!!
Don't buy either if you're only planning to use them together. Because GoodReader just won't work with FineReader's fabulous MRC compression.
But do buy FineReader to do fantastic OCR. Best I've seen, user-interface and all.
