Sure, it's not quite the one that Dick Tracy had, but LG showed off a prototype model of a watch phone here at CES. It sat behind a display case the whole time, but we did snag a few details about it: it will have Bluetooth, as well as text messaging. When asked how you would text message with it, the LG rep said that there's a scroll wheel at the bottom of the watch's face that'll let you scroll through letters and numbers. This sounds horrendously tedious, but at least making calls promises to be a bit easier--just pair it with a Bluetooth headset, and dial numbers using your voice. We have no other details other than that, though, and this is simply, as we said, a prototype.
