Several months ago, we discussed something called Nearby, a project that - at the time - seemed to be Google's effort to let "people, places, and things" know when a user is, well, nearby. It seems that Google is still hard at work on its effort to connect various devices to each other and their surroundings, but Copresence (an internal name for this functionality) may have a more specific scope in this effort than we first estimated, apparently including iOS devices in the fun.
Earlier today we got a chance to play with Samsung's Galaxy Beam (though photo opportunities were limited by lighting), and I have to say - for a projector phone, it's not bad.
The 1GHz dual-core processor hums along through Gingerbread (I know, I know - but an ICS update is surely in the works) nicely, and the 4" WVGA display gets the job done. While it's no flagship device, for such a niche piece of hardware, Samsung has done a pretty decent job here.
