The Infocast was a nice little product. I have one sitting next to me right now. It was not, however, a big sales success. I bought mine on closeout in late 2010.
Part of the problem was that Best Buy didn't know where to put the thing, nor how to market it. The 3.5" model was sitting next to the alarm clocks. The larger 8" model was sitting next to the Sony Dash in the picture frame area. You can figure out the rest from there.
The Sony Dash was also "chumby powered". It sold a lot better than the Infocast did, though. The Dash was in many ways the best chumby you could get in that it had a capacitive touchscreen, it had the least ugly industrial design of all the chumbys (IMO), it supported netflix, etc. OTOH it had gaping problems like Sony's insistence on using BIVL (which among other things makes the Dash the worst chumby for using Pandora and a few other services), it was locked down (unlike all other chumbies you can't just ssh into it and start hacking away), etc.
