Well, it's looking like profitable mining is dead in the water for the ordinary person. The only thing that might pick it up again is the rise in bitcoin value, making Sartoshis worth more, so even little bits are worth collecting.
So I've set up an Antminer U1, 1.5Ghz to solo mine to the solo.ckpool.org site.
I can't win Lotto, so maybe I can win this one.
I'll let it run for the next couple of years and see how it pans out.
If it works... I might just pick up 25 BTC...
Fingers crossed.
