Well, my wife and I are approved, according to the USCIS web site. Not much to say other than to give our details - we made an inquiry via our local Congressman in February, and he said INS was generating an RFE. Got that in March, responded to it, and INS received the response on 3/12/04. Both our I-485s were approved exactly 2 weeks later, today on 3/26/04. It was n EB-2 Employment-based petition, and I changed employer under AC21 in October of last year. I'm pretty sure it was the Congressman's inquiry that got the ball rolling, even if it did generate an RFE for tax returns, employment letter and paystubs. 
Yay!
