I finally got my Oath letter yesterday (5/22/10). MY oath is next month Friday - 6/18/10.
My N-400 timeline:

USCIS local office: RDU.
Sent N-400 12/19/09
PD 12/23/09
Check cashed 12/23/09
NOA 12/28/09
FP notice 12/29/08 (received 01/04/10)
FP Date 1/30/08 (walk in done on 01/06/10)
IL: 04/03/10
ID: 05/03/10 (N-652 interview results letter given)
OL: 5/22/10
OD: 6/18/10
Why is it taking a month to for Oath date? My lawyer was telling me that right now they are conducting Oath ceremonies on Fridays and if interview is in the morning, oath cermony can be in the afternoon or on Friday that week.
