That said, having considered Samsung's mirror less offerings myself before going with Fuji, the one huge knock against them for me is their sensors are not great at high ISO. If you do the comparison for other cameras in class on the NX210 (model above this one in Samsung's lineup, same sensor):
...it gets beaten like a drum above ISO 1600, even by the newer/smaller m43 sensors. That destroys a lot of the value proposition of a big sensor MILC over a P&S right there. Good image quality at base ISO, but pretty much any camera will do that. 'But more megapixels...' Unless you make poster size prints on a regular basis, or crop way too much, you can pretty much ignore the megapixel differences. The fact is, for not that much more money you can buy into a a better supported Sony NEX or Olympus system that outputs good quality images over a more flexible range of conditions.
The high-ISO argument depends on the type of shooter that you are. If you shoot in clubs all the time, or indoors in dim rooms without flash, sure... it will be an issue. But most of the models that have good high-ISO will run you at least $200 more than this Samy.
I looked at NX, NEX, Olympus, and Panasonic when I moved from my Olympus E-series DSLR to a CSC.
The need to shoot at high ISO was a non-factor for me, so I wanted good output (more resolution) and good controls, compactness, and convenience, all at a reasonable price (I know, I was asking a lot). I also wanted good resolution first and foremost. I shoot primarily landscapes, wildlife, and outdoors, and indoors I use a flash (with a diffuser). I did not like the reviews of the first generation m43 sensor. It seems like that would be a lateral move from my old E-410. I did like the reviews and test output from the NX gen 1 sensor (same sensor in the Pentax K20D and K-7 DSLR). DxO gave it great marks too. Again, this is for resolution, not high-ISO performance.
I wanted an optional EVF, which I don't use often, but I use whenever I go long and I like having the option available.
So, at the time of my search last year, I tried the Olympus E-PL1 and E-PL2 (ironically just about the same size as my E-410 body), the EVF-less NEX-3 and NEX-5 (NEX-7 was just too expensive, and still is IMO) and the glass for the NEX series is HUGE. I wanted compact. Panasonic GFs were all too expensive compared to their Oly counterparts, but seemed faster compared to the PENs.
Here's my breakdown of the CSCs. I actually like them all for different reasons (again, this is completely subjective... but might give a newbie some tips).
PROS: Controls: i-Fn is incredibly useful for example. Enough external controls to get shots fast. Output is bright right of the camera. Not a lot of PP needed (just point and shoot). Good small lens optics (the 3 pancakes are awesome). LENSES: https://en.wikipedia.org/wiki/Samsung_NX-mount#NX_lenses
CONS: firmware update process is very old-school and manual; long-term support; resale value (as in, none). The lower end series NX#00 and NX#000 do not have build in flashes.
PRO: Nicest dual-mode (still and video) of the small CSCs. If you shoot video the NEXs are pretty darn good and the optional mic attachment is nice to have as well (other CSC makers now have followed suit with the mic thing).
CONS: for me, the menu system was/is terrible, even with the firmware update. Not a shooter's camera at all, but if you are willing to dig in menus or just point and shoot then is an OK camera. Other than the not-well reviewed kit pancake, the other optics for the NEX are larger and heavier across the board. Also, no EVF option at the lower end. Awkward ergonomics. Left-tippy with a lens on.
PROS: during my testing, these were reliable with output. Good balance of sharpness. More natural looking on the colors then Sony and Samsung (IMO). Familiar menu coming from an full-size E-series. Built-in Flashes (not happy they got rid of it on the PL3). Good lens pipe-line with Oly, Pany, and now Sigma, and other 3rd makers on board.
CONS: Larger then expected (maybe because of the flash?). 12mp sensors (or gen 1 & 2) did not blow me away with resolution when I enlarged my test shots. Again, I shoot landscapes. I need and want the larger output. That said, if was to hand camera to another family member to shoot it the Oly would do quite nicely. Side-by-side price was $150 more than the Samy NX100 at time of purchase (for the E-PL1, the PL2 was $300 more).
Panasonic: really the same pros/cons as the Olys, but add $100 to the cost of bodies.
That's my take on these. I did not include Nikon's, Canon's, Fuji's or Pentax's offering in my analysis here... but here are my one word reviews:
Nikon 1: Fast
Canon EOS M: Slow
Pentax: Niche (Q or K-01)
Ricoh GXR: Modular
For a new buyer to CSC... if you just plan to Point and Shoot with the kit lens and never plan to expand, then just get the cheapest you can find. Just about everything I rambled through will take decent pictures.
Want lots of len options: m43 (Oly or Pany), Sony NEX
Want Canikon? Then buy Canikon.
Want speed? Nikon 1 series or Samsung NX300 (have to wait on see on this one). Soon others will follow with the Phase/Contrast hybrid focus.
Want good controls: I think Samsung's are good. The rest are pretty even... I did like the Canon during a recent handling (nice feel in the hand). And amazingly the Pentax Q's handling is quite nice too (especially considering it's size). The Nikons are all menu-based. No buttons. With Oly and Pany is depends on whether you are at the entry-level or high-end. High-end models have better controls, but cost more.
Want a built in Flash? Some of the Nikon 1's have them. The older E-PL1 and E-PL2 have one (as does the E-P3) A few of the GF3 and GF3 have them (but omit any accessory port).
Want smallest size? Pentax Q, E-PM Mini series. Pany GF3 and GF5 are pretty small and this NX1000 is pretty small too (smaller than my NX100 anyway).
So there's my non-scientific take on the current CSC's in the market place. Your needs/opinions may vary. Don't hate me for mine.
(As always) if you have a local store with these, go, put one in your hand, try before you buy. This is a great price for a CSC, but you need to see and try the menus for yourself. If you like it, come back to Woot and get the deal. Deals like these are the only time to get pick up cameras as they tend to be overpriced at retail and/or launch. Patience and smart shopping win the day.
Good luck making your decision buyers.
P.S. My 5-lens + EVF + GPS NX100 cost me under $800 for the entire setup. That was about $100 per lens and $300 for the body and accessories (EVF/GPS). These were all purchased from major retailers/dealers during sales and close-outs. That is why I went with Samsung: value at the time (right place/right time). If I could have gotten something for the same completeness and price point, I might have... but it's been a great camera so far. I suspect the NX1000 would be too.
