In the latest "pictofacts" post at Cracked, people contributed the design features of everyday products that bother them the most. Some have perfectly reasonable explanations, like the beeps that seems extraneous but help visually-impaired people, and Pringles, which are packaged for shipping and storage, not eating out of the can. The mouse that can't be used while you charge it bothers me, yet I understand that you shouldn't use a device while recharging. But as an old person whose kid lost the remote, this one really bothers me.
My TV isn't a Samsung, and the buttons do have faint labels, but I must keep a flashlight near the TV to see them. See the rest of the pet peeves about product design at Cracked.
