I’m not sure wether to be impressed that a power adapter had an OS, or terrified someone asked such a stupid question.
The two-tone green one is the eMate. It lives in the closet in our office. I’m pretty sure we have more computers than what he listed, there’s the artifact buried in our garage, and the jet engine in the living room (we should vacuum it again soon).
And no, I do not have an appropriately sized envelope to ship it back, maybe you should use the box it arrived in?
