(This sounds acerbic, but your comment is incredibly hard to take at face value.)

Yeah, I noticed that after writing it. Look, I have limited time and a complicated utility function. I can try to optimize where I think it would be particularly valuable to optimize (the decision to buy an iPhone is not small in terms of the accumulated costs or in terms of time investment so it seemed particularly worth paying attention to), but if I tried to consciously optimize everything I'd quickly run out of time to actually do any of the things I'm trying to optimize.

I recognize I'm opening myself up to further accusations of hypocrisy here, but I'd rather be hypocritical in the sense that I optimize some part of my life and not the other parts (and ask others to do the same) than be consistent in the sense that I don't optimize any of it. The perfect is the enemy of the good and all that.
