That is the one I say. It was the size of a double pack of gum. The keys actually were bigger than the picture shows.
I don’t think it was ever sold in the USA.
I wish the device had wider use. It is a fantastic concept. I bet it would be even smaller today.
You can buy them on the web for less than 200$. :-)
Add the Icuiti VR920 and an OQO computer and you are set!
