The NX210 isn't a revolutionary camera by any means. It has the same 20.3-megapixel CMOS sensor as its predecessor, the NX200, and the only huge new addition is the inclusion of a Samsung's built-in WiFi feature. By this rationale, the NX210 is "smarter" than its predecessor, as that's the adjective Samsung uses to describe its products with WiFi technology. The NX210 can not only transfer photos wirelessly from camera to computer, but it can also use its WiFi function to connect to smartphones and Samsung Smart TVs. This allows for some really cool options, like using your smartphone as a remote viewfinder for the camera, for example.
The NX210's $899 price tag is no different than the launch price of the previous NX200, so it's not like Samsung is asking for more money this time around. It's just a simple update to a compact system camera that did a decent job when we tested it last December.
