I suppose to try to get this back on topic, assuming that there is indeed a rear touch sensitive area on the PSP2, it might very well result in an entirely more natural way of holding a portable console, i.e. fingers at the rear, thumbs at the front/side.
Apple applied for a patent recently, which was to overlay (or more correctly underlay), faint representations of the finger tips from a rear touch area as part of the picture composition process, and thus allow the user to see exactly where he was touching, which certainly seems to have some useful applications.
