I agree with you that at this point, the best thing to do is to deliver what they have. My complaint is the same one we discussed a few weeks ago, that they have over-promised and under-delivered. This doesn't seem to bother you, and I'm trying to figure out why.
course it 'bothers me' that i will receive 15% less hash power than i was expecting. But in the time since i ordered, bitcoins are worth 800% more than they were when i made the decision to buy... so I'm significantly better off than i forecasted i would be...! (and the hardware is consequently worth a lot more... if it were sold today!) bitcoin mining hardware value correlates well with price of bitcoin.
but 'bother' is the wrong word. this is business. and my portfolio is diversified. mining is one of my areas of interest and i invest in other assets (properties, companies etc).
I've said this before.. but i'm less worried about taking delivery of my CT gear within a few weeks of schedule (at 15% less than expected hash rate) than i am at not receiving my HF gear, 12+ weeks later than scheduled... (regardless of whatever hash rate hf will over-delver). and i paid more for my hf gear than my ct gear, $/gh. bottom line, the delivery date is more important (read, more valuable!) than the hash rate.
