Here's an old one -- I don't know which wag came up with it: In supercomputer and parallel processing marketing, "peak performance" is "a guarantee from the manufacturer that your application won't run faster than this".
"Instant On", i.e., always on. Our product takes 30 seconds to boot, so the only way we can make it look like it turns on instantly is to have it on all the time. If you hit the "off" button, the only thing that turns off is the power LED.
@Duane: Bob from National TV gives it four stars. - And Bob, from national TV is whom?
It's like the TV adds for cars where everyone wins some type of award from "J D Powers and Associates" ... who the $%^& is J D Powers (is this a real person or a marketing fiction?) and who are his/her associates when they are at home?
