Maybe there's another thread somewhere for this but has anyone discussed that even with so much power of our Antminer S1, it's looking very doubtful that we're gonna get our ROI of 3.15BTC? [I'm not complaining at all; as I suspected it from the start before I bought it

]
I just want to focus the discussion on ROI wrt Antminer S1. What are your plans/contingencies?
I'm basing my numbers from playing around with the S1 since last night (about 13 hours worth of data); so not really significant sample size.
Many thanks to sushi and Bitmain for such a FAST shipping and so easy setup (literally 5 minutes; of course I was timid and took my time so maybe 15 minutes setup). I had everything ready; table, power supply, dd-wrt router brdiged via wifi to my main router (same one I'm using for my "downed" Litecoin miner).
Both of mine have been up about 40 hours, and I've already made 0.25 bitcoins
So not bad at all
And that was including some downtime, when I was figuring out about the power supplies and to get rid of some x's that were showing up, right now, both units have full oooo's
Just a thought when it doesn't become profitable to mine bitcoins
Why not switch to another sha-256 currency?
Oh and UPS sucks
Never had a good experience with them
FedEx is much, much better
