VIA launched their Nano CPU (formerly known as "Isaiah") a few weeks ago. This new CPU is similar to the Atom CPU: A low power, low cost CPU. The socket will be the same as its' predecessor, the VIA C7. It will come in two variants: The "L" (Low power) series, used in desktops, and the "U" (Ultra Low Power) series, to be used in mini notebooks and small formfactor devices.
Since the Nano was so new, there were very few manufacturers who had boards with the Nano on display. The only one we could find was VIA itself. We will have to wait some more months to see manufacturers distribute motherboards with the Nano CPU. We are anxiously following the developments, and looking forward to test one of them in our lab!
