So, What Features Did Sony Leave Out Of NGP?

Lots of stories yesterday about Yoshida-san's comments in Edge magazine about leaving stuff out of the NGP, but no one seems to have asked exactly what features they were.

My guesses would be:

1. 3D

2. Full-4G phone

3. SSD drive

4. Carbon fibre or Titanium skin (which would be a bit Apple)

5. Surround sound speakers

Can't think of much else you can throw into a portable, any more suggestions?
