Just in case you don't know, ASICMiner is mining with these oldhat tech 130nm "ASIC" chips.
No, Asicminer is mining with oldhat, but less older, 110nm ones. Labcoin and Btcgarden preferred to go to even older tech at 130nm and promise better chips. Great promises right?

ASICMiner has hit their glass ceiling and are basically floundering to be fair, simply because they are on old tech.
