[Skybird]

I checked the specs for the new version 5. There are three main differences, it seems to me. First, the device and the USB-cable and monitor-hook are connected via magnets, you can take off the device but leave the cable and hook/base in place. Second, the optical resolution, in the final effect, has tripled, which should make it more precise than version 4. And third, they say they improved the filter which sorts out unwanted background light reflections that could irritate the scanner, which hopefully should make a noticable difference in rooms that are not dimmed.
