If you will always be in the same location as all the systems you're outfitting, go with what you can provide adequate support for (Linux/Open Source, I presume).
If these systems are going to be scattered around the globe, go for Windows. Say what you will about Windows, but you'll find on-site support in damn near every country you travel to.
Macs might be a good option if they'll be deployed to major metropolitan cities only (NY, LA, London, etc.).
