I find the attitude of many folks on HN, arguably a forum full of logicians, baffling at times. I don't use 0 dollars to contextualize the cost of 1Password (or any productivity software). I value the time that I save with it. It saves me so much time, I don't mind paying $4, let alone $10.
Not paying for something because it's not free is being penny wise, pound foolish.
Perhaps there are situations where people are budgetting for the pot that the $4 a month comes out of, or are concerned about the number of services they are paying for and not receiving anything.
