They're good for what they are: consumer digitisation tools. Their turntables where their first product to hit the mainstream ("geekstream"?): audiophiles cringed, but thousands of iPod-wielders actually started listening to music they only owned on vinyl. Same with the cassette deck. We all know what a pain film digitisation is. Ion's market is analogue media that would otherwise become or remain inaccessible (or at least unaccessed). It's not archival, but it's not meant to be.
Do I own any Ion products? No, and I have no desire to. I think all of us here demand archival quality from hybrid workflows. However, Ion is not courting us as customers: they're courting the people who are choosing between "throw away all of the old negatives" and "scan the old negatives before we throw them away".
