[R-sig-ME] lme vs. lmer

I've started working through Pinheiro & Bates, 2000 and noticed the use 
of lme from the nlme package. I am curious if lmer from lme4 has 
superseded lme or if lme still holds its own? The reason I ask is that I 
have taken a few classes where we've solely used lmer and just read 
about lme today. If both functions are on equal footing, can the 
p-values from lme be trusted?
Thanks!
Chris
