By "geographical usage trends," do you mean the type of devices being
used, or type of service plans (for wireless), or do you mean what the
users are using the devices for, or how often, or if spending on PDAs
is increasing in that region?

Ksm,

Below is some information I found on PDAs.  It is not geographical. 
In any case, I read a report, which I can't find, that talked about
this a couple of years ago.  Typically the West and East coast are the
most inclined to get PDAs.  The south is the leseat likely.
