AI Question (spoilers)

[- Joy -]

I went to see AI tonight (to see the HP trailer on the big screen, of
course), and there was something about the plot that really confused me.  I
know a bunch of you have seen it, so I figured I'd ask here since I couldn't
find a discussion group specifically for the movie.

In the end, did David become "a real boy"?  He'd said before that because he
was a mecha he could never really sleep, but the voiceover at the very end
seemed to indicate that he was able to fall asleep and dream.  If he did,
what was it that prompted the change from mecha to orga?  My dad and I can't
seem to agree about what actually happened in the end, so we'd appreciate it
if you could settle the debate.  Don't forget to include spoiler space
when/if you reply... Thanks!
