It's important to understand that the ActM hardware is modular.  One of the fair criticisms we hear from people is that it's just a marketing gimmick as a top of the range 24TH miner isn't just your standard PC case full of goodies, it's a big server rack of hardware which requires a decent amount of space, and presumably management.  Ultimately it boils down to how much bang you get for your buck and what fits your budget, and how it compares to the competition.

Entropy's use of the word obsolete made his sentence meaningless.  He was merely trying to have a dig by suggesting there are 'bigger' chips out there, but in reality our eAsic chips are among the leaders in terms of energy efficiency and price per GH.

Edit:  Entropy's post above accepts the fact that ActM's business model works provided we get to market first, making mention of the fact that against our competitors we haven't done so.  That's a little strange given the fact that in his list of competitors, only one of seven have delivered 28nm hardware.  Go figure.
