P.S. After crowing about seamlessness and all of that, I was given a good kick in the you-know-what by OSX Lion, which apparently will no longer support the software and drivers I need to run my ancient Canon scanner. Goodbye scanned typecasts! Using a tripod and his fancy digital camera, J took photos of my typecast and saved the day, and I will need to figure out how to deal with this new hiccup going forward, taking photos of the pages that are fairly decent.
I don't mind getting rid of the scanner - it was bulky and cumbersome anyway - but I hope I can keep up the image quality of the typed pages with a digital camera. We'll have to see. In the meantime, I have learned a valuable lesson: not to type on every possible inch of the page, as I have tended to do, leaving me very little space to allow for cropping afterwards.
