Things that still need fixing
Samsung needs to introduce a model with more control dials.
(see Fujifilm X-S1 which even at a few years old, has one of the best implementations of controls ever - if Samsung had so many controls, plus their amazing Fn-menu, they would have an unbeatable user interface both for simplified use and advanced users alike).
The new tilt screen is very nice: it's nice that you don't have to swing it out and flip it over as on the nx20 - although not everyone will prefer this, it will definitely appeal to many people who don't like the idea of the flip out ones yet don't want a fixed screen.
Samsung needs to authorize downloads of it's remove shutter application onto more devices: currently, even if your phone has the right version of Android or higher, the right amount of screen resolution or higher, enough processing power and built-in memory, that doesn't mean that Samsung will have given Android Market the green light for a download to your phone. So be aware of this before buying this camera: WiFi may not work for you.
Samsung also needs to IMPROVE the remote shutter application, or open up it's code to others who wish to make an app for their cameras - pick one: do it, or move over and let others do it for you.
@DPR: in the optional scoring sliders, please add one for ergonomics (screen/handling), and one for controls (buttons/dials/menu).
