I also had a surprise last night. With no prior notice or tracking number my other two X1's arrived from Minersource. Ordered and paid for in mid December.
ROI on them is about 2 years. Guess its time to try to unload them or solo/solo-pool and try and get lucky.
You'd have to be really, really lucky. At 100GH/s your average generation time for a solo block is over 47-1/2 years.
Unfortunately, even your 2-year projection to break even is hopelessly optimistic - unless you have free electricity, your power costs will exceed your earnings after just a few more difficulty jumps.
BA has well and truly fucked us.
