It may seem like a no-brainer, but until recently there was no camera with a wi-fi receiver that would allow users to share their photos on social media sites directly from the camera. Apparently, Samsung has recently released one.
I feel a lot of people wanted this functionality, but no company really understood that until very recently. For the first time people will be able to share high-quality pictures on the go.
Following the lead, I think most camera producers will include Wi-fi functionality in their cameras in the next 3 to 6 months. On a side note, I am not endorsing Samsung cameras (I prefer Canon), but in case you wonder, the models with this functionality are NX1000, NX20 and NX210.
