I have followed AP over the years and own just one. Mine is the iconic RO E-series with silvered waffle dial in ss with bracelet and "AP butterfly" deployant. As a matter of fact, it is my daily wear watch, despite my original concerns of scratches and damage that these watches are susceptible to with the many angles and contrasts of polished and brushed finish! I have found it to be of very high quality and verstility from jeans to suit attire.
Kudos to you for asking some very valid questions based on current trends and topics during the interview. To answer your question, I think some have challenges with the LE versions of the ROO for these reasons:
1. Seem to be somewhat frequent with minimal, insignificant (read: not innovative) changes (ie: colors on dial, hands, etc.)
2. Why does a brand like AP need to do this anyway? (ie: Shaq version, JayZ, etc.....) realizing some are for charitable and noteworthy causes, the endorsement/LE approach taken at times seems a bit out of place for a brand of AP's history and market niche - somewhat into the trenches of a more mass audience, mid-level brand marketing approach.
Points above said, we all need to realize that AP is not just a static entity and is in the business of making a profit to survive. As such, they obviously need to be in their target market segment space with new offerings and interesting pieces to keep business moving forward. The caveat here is that I do not profess to know or even follow all of the various permutations of ROO special or LE's out there. It seems from my limited knowledge, that much of this accelerated after the Montoya edition, which was truly innovative in the use of materials and design in the way it also followed the ROO key themes. These are just my thoughts and not meant to stir the pot, as I am one who does not particularly favor the look or size of the ROO on myself. I am perfectly fine with my plain and versatile RO!
