How is OneNote's OCR? I also use Evernote and it does a great job of recognizing and indexing text on photos of whiteboards.
You said you chose something lighter weight. What did you end up going with? I've used Evernote for years but am unhappy with the direction the program has gone. The new CEO seems to be refocusing on the core purpose (capturing and remembering) and so I'm contemplating sticking around for a bit.
