I think it's perfectly okay for bitmain to mine before selling and shipping. It's not like you paid them money for a preorder and they use your money to build miners, mine on them, then ship it to you months late.
Bitmain is different than other ASIC's companies. They are trying to setup a win-win situation for themselves and customers. Sounds good to me.
Agreed. They are the fairest asic company I have dealt with. One of the few that actually has product on hand to sell.
I think the s1 will go down in history as the last great asic machine for the masses. I should edit the wiki later this summer.
Yep Bitmain is heads and shoulders above the rest.
