At home and at work, one of the most important form-factor changes in design history has yet to happen: the re-design of indoor work space to center on computers instead of desks. The re-design will be based on the “large screen computers” that I’ve been writing about for years; today they’re a routine matter of assembling the right parts. The screen (any modern high-def TV) is six or seven feet away from the user; you lean back in a comfortable chair with the keyboard in your lap. The change is important, because eye strain is a problem when your eyes focus on something nearby; putting the screen farther away is a significant improvement.
