If you want to upload pictures from your camera to Facebook or Flickr without having to make a detour to a computer, you could get a camera with built-in Wi-Fi support. Or you could keep the camera you already have, and add an Eye-Fi Mobile X2 card. The X2 works like any other memory card, and also lets you upload your shots to the internet over Wi-Fi â€” or it can transfer them to your smartphone, even if you're nowhere near a Wi-Fi network. So, go ahead and impress your Instagram followers with pictures you'd never be able to get with your phone. Just make sure to charge your camera's battery first, since the X2 needs a lot of juice to transfer those files.
