On an offtopic note... seems like KnC customers are having a lot of problems
a) The fire extinguisher was not included.
b) Not enough packing. (leading do many problems with fans falling off, bad heat conduction)
c) Not shipping on the dates expected. (with no talk of compensation so far)
d) Serious problems with hosted miners. (with no talk of compensation so far)
a) LOL
b) supposedly being addressed. We will know in a few days
c) agreed
d) compensation was offered and in some cases received. 1 bitcoin per day not hashing from expected delivery, and 1 month free hosting.
My personal thought on this is that they made a hell of an effort, and hit some unforseen (largely due to optimism) speedbumps. So far, they have been very up on things up to sep 30th, after which they somewhat dropped the ball. According to Bitcoinorama, they've all been working themselves ragged trying to fix everything. I suspect they'll get it all ironed out to the satisfaction of most of their customers. Having followed their development since the day they posted their proposal, I will have to say that there will be some who are not satisfied no matter what. I think those few can be discounted, because there is no scenario under which they would be satisfied.
The extreme variance in hashrate is troubling, and I suspect there are hardware problems that have not been addressed by KnC, though we simply don't know what they're doing. Again, I think they will bend over backwards to make it right. These boys have pride, and skills. That's a dangerous, but usually useful combination of traits.
