Like an awful lot of people, I essentially always have my phone on me. Well, now that means I've always got a light meter on me. Cool.
I'm not sure that I really see the need for the Lumu proposal---if I have to remember the plug-in sensor, I might as well have to remember a regular light meter---but it certainly doesn't hurt me any. I don't see what y'all are so upset about. You'd rather people *not* have another option for metering? Or is it just about scoring points by showing off your anti-technological principles?
