Full disclosure: the D3 is the only official Digivice toy I ever actually owned, so I’m probably biased, but this is still my favorite design. Of all the Digivice designs, I feel like this is the one that best struck a balance between Memorably Iconic and Believably Functional. Some Digivice designs are instantly recognizable and cool-looking, but in a way that never really looks like anything other than a toy. Others really are convincing as advanced pieces of technology, but in a way that reduces them to clunky, forgettable tools. The D3 is the one that really strikes me as a thing someone would use in real life, and look cool doing so.
