Remember the Slate Mobile AirDesk, which I described as resembling a “neatly-drilled chopping board”? Did you look at it and think “I like that. I could see myself using one of those, if only it was a little smaller, so I could carry it in my bag.”
If the answer to either of these is yes (or to the second question, mostly), then you will be ecstatic at the news of the SlateGo, a slightly smaller version of the laptop lap-desk.
