I am the happy owner of a Sprocket Plus myself, a great little product. I have printed quite a lot of pictures with my Sprocket, and they are of good photo quality. Of course they cannot be compared with photos of professional quality, but I am more than satisfied. As far as I am concerned, I cannot see that neither HP nor Zinc guarantee the photos to last for ever, or for a certain amount of time. It is well known that colour photos will loose some quality when exposed to sunlight for some time. The best way to preserve the photos is of course to keep them in albums, or some other way in order to prevent them from daylight for longer time. Sprocket is such a new product, that I guess that nobody have enough experience to tell how long their printouts have lasted.
