These are supposed to make you feel calm while you're using your computer, so you like their product more. Good grief, people will do everything they can to make more money, won't they? I think I've posted this before--I am convinced that the food court at one of our malls was deliberately designed to have sounds reverberate through it, and with uncomfortable chairs, so that customers will want to hurry up and get out of there, making way for more people to spend their money. Mind you, it looks nice: lots of big potted plants, lovely-looking wooden chairs and tables. Very subtle effects. I don't hate greed quite as much as I hate lying, but it ranks right up there; it's just so unnecessary.
