I just bought the deal on the Teach the Text series. I already had 2 of the commentaries on kindle, one of which was 1 Corinthians.
It's not a big deal, but I've noticed that many of the photos - in particular scenes like the above - are cropped or faded out on the one side in Logos, and some appear very small compared to kindle.
In this example, the caption says "This view from the Acrocorinth shows modern areas of cultivation that were probably also used for farming in ancient times." However if you compare the two, in Logos a portion of the farming is whited out, reducing the impact of the photo. Strange that this happens - obviously nothing can be done about it, but I wonder if we're losing some of the benefits of the photos.
In the section on 1 Cor 7 there is a photo of a Roman urn from the 1st century, which is very small in Logos, but in kindle it is so much bigger that one can clearly read the latin inscription at the top, which might be useful for some.
