Post-PC Pain?

Tablets are replacing PCs in many work environments, including factory floors, hospitals, and even restaurants. But the verdict is still out on the long-term health effects of using slates for extended periods. A 2011 medical study by Harvard and Microsoft shows that tablet usage has a greater impact on head and neck posture than conventional desktop and laptop PCs.

A one-pound computer may be easy to hold for 20 minutes, but carrying one for several hours is another story. Touchscreens raise ergonomic issues as well, particularly if the user keeps one arm in an elevated position for hours to tap the display. To be fair, keyboards and mice have long been linked to repetitive stress injuries, and are far from perfect.
