Who is saying 4 - 6 weeks? No one but the same old tired trolls.
With the GPUs you can mine and game and crack encryption but these BFL units have close to 0 resale value and you cannot game or hack with them.
Completely irrelevant. ~200w + supporting hardware for ~650 MH/s is not anywhere close to 60 - 80w @ 800 - 1 GH/s. You only need one or two cards to game with, the rest are completely superfluous and just power hogs. 99% of the people mining do not, will not and probably don't even know how to or why they would want to crack encryption with them.
Completely false dichotomy. Just because a new or more efficient ASIC miner is released does not somehow cause an older miner to suddenly stop functioning or generating income. If someone else were to release a 1.2 GH/s unit for roughly the same price as the BFL unit a month later, do the BFL units suddenly stop producing 800 MH/s? No... they continue to mine.
I do, however, agree that a 6 month warranty is a little shallow. A 1 yr warranty would seem to be the right thing to me. But the argument that if it's going to fail it will fail within 6 months is fairly sound as far as these things go, but that is a doubled edged sword. If it's likely to not fail at 6 - 12 months assuming it lasted 0 - 6 months, then increasing the warranty shouldn't increase the support burden all that much.
Thanks for being the voice of reason.
