It's going to be damn close to BTC break even by the end of 6 months of hosting. By then I'll have around the same BTC that I would have had purchasing them AND a piece of history (The Jupiters). They may even still be profitable then and continue mining 
And that is the criteria that should be used, glad we agree
So I paid 7000USD for a Jupiter and if by any miracle I mine and sell BTC for 14000USD then I did bad?
It's not bad, but the profit has come from the rising BTC/$ rate not from the Jupiter. Any hardware needs to be valued in the number of BTC it cost and the number it gives you back.
until you are living your life entirely on bitcoin, not making the full btc you spent back means fuck all. Life runs on fiat right now and thats the ROI that actually matters.
And if you keep thinking that way, you'll end up poorer. Think of it all in $ terms. Imagine it's a $ mining machine. You have $100 in your pocket, I will sell you a machine that makes $1 coins, if you buy it and it only gives you 60 coins it was a bad investment, if it made 120 it was good
