Having just switched from a 32 bit kernel and apps to a 64 bit kernel 
and apps on the same hardware (Core 2 Duo E6600) that the machine seemed 
a bit more responsive than previously.  I wasn't looking for an 
improvement, just noticed that it was all a bit "snappier" than before. 
  Apps load a little faster, machine seems a little more responsive.

This was totally unexpected, but a nice surprise.
