When innovation stalls...
I think this was in some of the CES videos a few months ago. The concept isn't too new, several manufacturers have had special cycles and doo-dads for scrubbing out stubborn stains as well as a switch for running water.
The Samsung sink feels like a big attachment, perhaps rarely used, that would be an impediment to loading/unloading. Does anyone know if it's detachable? Like the GE Mini-Basket (and many filter pans, softener dispensers, etc.) it would probably end up on a shelf and eventually pitched in a few years.
