I always appreciated CueCat because years after they failed I bought one on ebay for $2 and used it as a barcode scanner to categorize all my books. Worked great for that. :)
> I never thought it would go anywhere because who would buy hardware just for that? But I did kinda admire that they tried.
I think they gave away the readers for free. I had one at one point, and I certainly wouldn't have paid a penny for it. I think they were also the basis for quite a few barcode-based hobbyist projects at the time.
In retrospect I see it as ahead of it's time. The idea of "place a computer readable label on things to send you to a special website (etc)" is still alive and used today in the form of QR codes. The hardware problem ended up solved by convincing everyone to carry a computer in their pocket and image recognition, but the central idea is pretty much unchanged.
The Dallas Morning News sent them to subscribers with their Sunday paper back when this was a thing, because they realized nobody would buy one. It still failed miserably.
