I would settle for an ultraportable USB-attached reader device that scanned microfilm/microfiche, with a draft mode that lets me preview a low resolution real-time display via the USB on an app on the laptop to position the film/fiche, and a high resolution mode for scanning into the app. I can understand the film/fiche writing machines being hideously expensive, but I have yet to find a reader that is built for the XXI century digital-oriented demographic. Of the readers built recently, they're all expensive, and are designed with firmware, instead of a design orientation of dumb manipulable hardware (preferably with open documentation) driven by modifiable software.
