There's lots of little things in the first movie that meant nothing to you the first time, but now they really make you think, now that you've seen the whole trilogy. My personal favorite:
The Oracle: (about the vase that Neo breaks) "I said don't worry about it. I'll get one of my kids to fix it."
Since we now know the Oracle is the Mother of the Matrix, we can only wonder, did she mean one of the kids in the front room? Or perhaps a program?
