I had to laugh when I saw the product listing for this "mobile desk." The contraption, which is made of powder coated metal with a vinyl saddle, allows you to "travel around your workplace without leaving your laptops or documents behind," according to the listing in the online store Opulent Items. The desk-on-wheels, which also comes in a mind-boggling tandem model, seems ergonomic enough to serve as a space saving work station in the home, but I have a hard time imagining anyone using it to travel around the office, unless you're trying to get a laugh. And those laughs won't come cheap: the Mobile Desk costs $500.
