I'm not sure what has generated this "fairness" topic, but given what you have stated in the above link, and with regard to what users of the earliest versions of the Windows product expected, and received relative to the price then, there does seem to be a disconnect between what is currently offered for both platforms for the same money. JR isn't saying so, but are they needing to charge the same price for a lesser product because they're not selling as many Mac versions? I can understand this but only up to a point--that is, they're possibly not selling as many because it's still in beta, and word of mouth isn't yet to the point for all iTunes users knowing there is a better alternative (leastwise for music).
IMHO, what is unfair is that MC18 for the Mac will probably never be anything other than beta, while JR moves to MC19 and asks us to pay for yet another beta. As far as I'm concerned, it isn't about the money--rather, it's more about a marketing practice that is unfair. In all fairness to these Mac users, who have contributed to making this version what it is today, we shouldn't be asked to pay out anything additional for a finished product--we've already paid.
My opinion having been said, I'm likely go go along with whatever LR wants--iTunes and the alternatives are that bad.
