I needed an extra large digital photo frame that did video as well for a traveling display, and the NIX was certainly the right price, and had the right "functional" look for where I need it (no wood frame, and no artificial picture matting). Overall it is best frame I have yet used (I own two smaller and have done a lot of shopping). Brightness and color are excellent. Processing power seems up to any jpeg you might throw at it. Controls and navigation are the best I have seen yet.
The only drawback is that it DOES NOT play HD video, and, despite what the website and instructions say, I have not been able to get it to play any .mp4 file, or MPEG-4 coded file, at all...or for that matter, .avi which they also claim it will play. On the other hand, my 720p HD video plays fine when transcoded to 720x576 Letterbox style, MPEG-2, with MPEG-1, Layer 2 audio. (I use a free converter called "Free Video Converter by Extensoft"...quick and easy.) Once transcoded, the video looks very good! You would not guess it is no longer HD.
This really does, for me, take the place of a laptop and monitor for my travel. Excellent, and a great value.
