$30k for 20 ghash/s. The breakeven is ~15 months assuming difficulty doesn't increase AND mining rewards doesn't halve at the end of the year. And plus you won't get this until July. Realistic breakeven is closer to 5 years. Add hosted/DRM mining and 90 days warranty to this. Thanks, but I'll pass.
This appliance isn't targeted at the hobby-level miner. If you have a few machines in your basement, keep on GPU mining. Chances are, you don't care about data center costs or power costs. But if you want to mine as a business, the ASIC model can't be beat in terms of profitability.
Ok, let's assume data center costs and power costs are $0. Mining this at 20ghash/s nets you about $2000 a month. Let's assume both bitcoin price and difficulty either don't increase or cancel each other out. So you get 5 months at $2000 a month, and when the mining rewards halves in December of this year, you start making only $1000/month. It will take 25 months to make back your initial investment.
You guys really need to rethink your strategy. Maybe leasing makes sense. But purchasing your device doesn't make any sense if it doesn't break even for 2 years (which doesn't even include the data center and power costs!)
For comparison, The BitForce Single takes 8.8 months to break even and the BitForce Rig takes 6.5 months to break even. And these 2 numbers assumes power costs $0.30 per kwh.
