Not lately. I received my plastic card in Feb 26, 04. My I-485 was approved on 9/17/03. The online message changed on Feb 24 to:
On February 24, 2004, the card order was completed and we mailed the applicant's new card directly to him or her. If 14 days have passed and you have not received this card, you may wish to verify or update your address. To update your address, please call the National Customer Service Center at (800) 375-5283.
It took a little over 5 months. Some people have gotten it in 2-3 months. All depends on USCIS.
