The major issue with this is most pc's are now coming with gigabit 
ethernet connections.  Going to gigabit speeds is such a huge 
improvement it's often worth the extra expense to add a second drop to 
each location.  Profiles will load faster, Outlook-exchange interactions 
work much cleaner.  When gigabit capable phones are more prevalent, this 
  becomes a non-issue.  Right now, there are very few gigabit phones and 
none that are affordable.
