According to Corinna Vinschen on 3/12/2008 11:51 AM:


  When last access time functionality is disabled, utilities that rely on
  sst_Atime attribute will not work correctly. For example, the U option
  of ls utility will not work as expected unless last access time is
  enabled."

*Sob*,

Agreed :( Remind me to not switch to Vista any time soon.

But no different than using the Linux mount flag of NOATIME - except that with Linux, you can make the decision on a per-mount basis rather than globally, and the decision is not forced on you by a default installation. atime updates really do lead to slower performance, so even though POSIX requires atime on non-read-only file systems, I can understand the performance gain for skipping it.
