A lot of cool things can be found when you tear apart code and start digging around.  This is the case when the Webtop code for the Motorola Droid Bionic got busted open, and some device code-names were discovered.  Besides a few we already know -- the Olympus, Sunfire, and Targa are the Atrix, Photon, and Bionic, respectively -- we see "common," which we assume is a generic term used to cover all devices with Webtop enabled. And now we see "edison."  A quick search of the Internet and the various sites in China that usually have information about this sort of thing turns up a blank, so we're pretty sure this is the first mention of a Motorola Edison to be found.

As for what the Edison may be, there are a couple logical choices -- the Atrix should be seeing a refresh (the MB865), and of course we can't forget what was leaked out as the Droid HD -- a Photon-esque shaped device that's thin and has some sort of SIM card slot on the side.  And then again, it could just be a name that was tossed around and then scrapped; we've seen that a time or two as well.  There's always something new and better on the horizon, but we can't help but get interested when we see it in black and white.

Thanks, Braden!
