Sure you can use any Win32 tablet PC to control the system via WiFi. Personally I used Sahara Slate PC i412T
under 0710. PPC will also works via WiFi. Only mobiles phones - with Java support, S60 or Treo uses Bluetooth.
For what I want to to, Input to local orbiter, and pass on commands to the jobsite do you have any specific recommendations?
Don't understand clearly what do you need. Could you clarify, please.
