Love this breakdown and summary. Will be saving it for future reference.
Yes, thats a very good breakdown if you are planning to start mining at home. But keep in mind that these are just rough figures and that philipma did not mention many other factors that can affect your profitability. For example, mining difficulty that will inevitably go up, risk of hardware failure, etc.
Touche, yes. I was taking their comment from the angle of "you're not going to make money" ... which is what you're saying, too, just a little more direct.
