Everyone seems to be improving their cameras in smartphones, so why not the reverse? The Samsung Galaxy Camera EK-GC100 is a full-fledged Android device that, courtesy a SIM card slot, connects to AT&T's network. So, once you take a photo or video, you can instantly upload it to your social networks. And, with a larger 16-MP sensor than can be found on most smartphones, this camera can take better photos, too. But is it worth plunking down $499 -- plus at least $10 per month for data -- so that you can update your Facebook account wherever you are?
