Of course, the logical extension of this school of thought is a compact with a tiny, tiny camera and a mirror-sized LCD screen - the idea being that milady could have a corrected view of her makeup instead of the virtual, reversed image given by an actual mirror... and it plays SD chips back, too.

The economic lines will cross when it becomes less expensive to knock off a high-resolution LCD screen that size, wired up to a single-chip camera/image processor built into the screen itself than it is to make an actual mirror. We'll see them made in rolls to be trimmed and pasted into thin plastic frames.

Eventually, the words "digital is cheaper than analog" will be a truism, too obvious even to speak aloud.
