Wootalyzer was doing it earlier, but apparently the mods were deleting their posts. I saw one early on, and when I refreshed it was gone. Perhaps they gave up.
This is a modified version of the Chumby. It runs some of the apps though there are restrictions, so if you are a developer beware it is harder to develop with.
The advantage of the Dash is a nicer user interface and the fact that is supports Netflix Instant Streaming, which might make it a very nice deal.
With the new Chumby 8 announced there is supposed to be support for Actionscript 3 coming soon, who knows if the Dash will get the update.
EDIT: there is no battery support for this(it has to be plugged in), which to me makes it personally less attractive because you cant easily use it in bed/carry it around. However it could be a great bedside way to watch some Netflix for others.
