Will these be able to adapt in the future and keep up with changing software?
In the opinion of those who bought some, should I just buy GPUs? Is it worth it? I can get 350-400 khash/s out of a GPU for half the cost.
I love the idea but think maybe I should wait for better revisions and/or competition to hit the market.
If you have large amounts of free power and can dissipate the heat, GPUs are probably a better option than current generation ASICs. I think in Q3/Q4 we'll start to see a lot more competition and hashing power from ASICs. Right now GridSeed is the only ASIC shipping.
