Why You Shouldn’t Buy a Touch-Screen Laptop

"When you touch a tablet or smartphone, you usually bring it closer to your face. However, with a clamshell laptop, you have to reach across the keyboard, which is awkward at best and injurious at worst.

“You are going to have to be doing a lot more reaching and a lot more movements of your wrist and your hand if you’re going to be typing and then doing the touch screen,” Cindy Burt, an ergonomics expert at UCLA, told Laptop Mag when we interviewed her for a previous article. She said that retail workers who have to extend their arms and poke at touch-screen point-of-sale systems all day — a gesture similar to touching a laptop screen — have developed shoulder problems."
