To my eyes, the 2 main advantages of this NIkon over the competition could be:
- battery life - this is the main issue with the Nixvue Vista (sold as Delkin in the US),
- shock protection.
WEather it will be able to display Canon RAW or not, I don't know, but it will be able to display previews of NEF for sure.
However, based on the experience I have had with the Vista, previewing is of very little value. I would never delete an image, even if the small preview looks poor.
Plus, the capacity of the HD is such that there is no need to delete images.
Best regards,
