The Japanese concept design community known as Cuusoo has produced a concept device so practical and tantalizingly well designed that it's a wonder it doesn't already exist. Created by the Japan-based designer known as Marimo-san, the concept illustrates a cell phone that would allow the user to detach the screen portion of the phone thus allowing one to engage in video phone calls on the go. Marimo-san offers several versions of what the various attachments would look like, from widescreen PC-style to dual screen video viewer. Such a cell phone innovation would go a long way towards speeding up the convergence of the PC and the cell phone so it's likely that this is in fact a design we'll see released into the marketplace sooner rather than later.
