Partly yes, delivery date promises then constant delays due to in part what is probably just poor engineering from the ground up. Avalons are ugly to look at but from what i've read they seem reliable and reasonably efficient compared to any GPU rig. (Butterfly Labs if you're reading this, they don't need to be pretty and they don't need to be super power efficient (as nice as it would be) mining 50Ghs at 600 Watts is fine by me.) We really need a new competitor in this field someone who's ready to deliver now (a man can dream). That being said beware of scams tons of those out there right now.
