Before we begin, have a look at two phones - one, the LG Optimus 3D, and two, the HTC ChaCha (aka one of the several Facebook phones to reveal themselves in the past 40 or so hours.) Alone, these phones have chances of becoming popular phones for a while, maybe a few months of bigtime sales, then on to the next one, if you take my meaning. But what these two phones being released at relatively the same time means is that the social aspect of mobile has entered the hardware realm.
Being of course aware that cellular has taken over the telephone business because it allows us to be social much easier and more constantly than ever before, the implications of the two phones we're talking about here are nonetheless significant. First, there's the HTC ChaCha with its physical Facebook button, then there's the LG Optimus 3D which is essentially the starting point for LG and Texas Instruments plan for Me-D, a plan which includes 3D recording the sharing in its infrastructure.
The HTC ChaCha is the more blatant in its method than the Optimus 3D in that its physical Facebook button notifies the user instantly that this mobile device is optimized (or at the very least in cahoots with) Facebook. Of course we know that HTC has worked very closely with the Facebook crew to make sure this phone is a Facebook sharing machine, but its because this social network has literally become a physical button on a device that's especially important.
With the LG Optimus 3D, the worth for the evolution of the mobile industry is the ability not only to view what they're calling 3D content, but the way in which with this device you're able to capture and share 3D content. It's not a new media, but it's certainly the first time the media (and we're talking about 3D content here) has been available in a device with a process so complete - you can capture and share and view the product from the same device.
The legitimizing and propagating of two items here, one of them a form of media, the other a brand that signifies a piece of the current state of digital communication. Both of the devices this new situation rides in on look lovely, but even if they were complete vapor, we'd open their deeper meaning with open arms. Long live the ever-changing nature of communication.
EDIT: BONUS read Ben Bajarin's analysis of the situation over on SlashGear with a post by the name of HTC's Facebook Button is the Start of Something Big.
