Thin clients for public safety?

Hello all,

I am seeking information and a source for a thin client solution for law
enforcement vehicles. We would like to locate an alternative to the current
laptop path we are on. Our long term goal is to utilize thin clients or
even PDA's in the patrol vehicles and have Terminal Server on the back end
to deliver the data and desktop. If anyone has information on a source for
a mobile thin client, I would greatly appreciate it.

Thanks

Steve
