I wish people would stop calling them apps. They're not applications, they're programs. An application is how a program is used.

My pet peeve too, even more than referring to directories as folders. I even have to correct myself sometimes when I catch myself saying (or even thinking) "app" or "folder," the messaging is so pervasive. Every single aspect of being an active (as opposed to passive) user of technology is an adversarial process every single step of the way. Even on the mental level, with what word comes to mind.
