Right under 7 billion. Good time for miners :/
Trying to do the math in my head here. A BFL Jalapeño does ~100 diff 1 shares a minute. So drop 2 zeroes off 7 billion and you find a block on average every 70 million minutes.
Things people said why ASICs were good for Bitcoin.
1. Less heat – No
2. Less power – No
3. Stronger network – this only counts if you are a ASIC chip maker, everyone else no
4. More reliable, less babysitting than GPU. No
I miss GPUs right now
