Peter, I understand all that. The question then is when the marketing speak far outweighs the real life applicability of technology. I, for one, know that buying highest end audiophile gear will be waste of money on me. The same would probably hold true if I mortgaged my life and bought myself full complement of Leica S camera and lenses... One has to be able to understand when the next upgrade is technology for technology sake, which still has its right to exist, but knowing that will allow better manipulation to get the results one wants to paraphrase what you just wrote.
