As it's only been available for a short time, I think it remains to be seen how good the build is.

Personally I think they are way too expensive. A standard netbook, while it will be a bit slower, costs a fraction of what one of these cost and for the most part handles everything I need.

My netbook also has longer battery life.

The ZD net review mentioned it did not have a dedicated graphics card, so if your work is heavy graphics, that may be a concern.
