I disagree.
ASIC preorders are high risk but they are also high reward.
Take for example Avalon's first batch, which is expected to ship 300 66Gh/s units. This will double the network hashrate. A single $1300 unit will return $2200 in a month ($1460 if ASICMINER brings another 20 TH/s online). This is a ridiculous return on investment that is more in line with investing in a startup than purchasing a consumer product.
I placed early preorders with all three vendors. I did this with the assumption that my payment would be used to fund development. I also assumed that I risked losing my money to scams or simply a failure to deliver due to technical issues. When I ordered the upgrade to my FPGA minirig, I factored in a 10-20% chance that BFL was pulling a long con into my calculations. The potential benefits of receiving the first batch of 1TH/s miners out-weighed this risk. If there was no risk, why wouldn't the ASIC companies just mine themselves until it was only marginally profitable, and then sell units to the general public?
There are two optimal points in time to buy ASICs:
1) First in line (high risk, potential for high reward)
2) After the product has shipped (low risk, low but more deterministic reward)
Everything in between is only slightly less risk than being first in line, with significantly less reward. Should you preorder an ASIC now? Probably not... why not wait until someone delivers instead of handing over your coins to get in the back of a huge lines? However, I believe that early ASIC orders, while speculative, had a positive expected value.
With regards to customers who placed orders with BTC, it is unfortunate for them that BTC has more than doubled, but no one could have predicted that. The exchange rate could of moved in the other direction. There were many opportunities to hedge this risk.

THIS!
Hopefully 5 years from now bitcoins will still be around and traded, and people will just look back on all of this pre-order bs as a blip on a radar. Some people will have made a nice profit by investing early and others will wish they did. It will probably make an interesting book for someone to write in the future.
