Customer is asking for a demo and aside from 2D scanner are leaving the decision in device config up to us. 

They are using SAP Console and could move to ITS Mobile within the lifecycle of the devices selected.  We would like to put the right device in their hands as we may only get one shot at a demo.  (They are initially looking at manufacturers with a “go, no-go” mentality.) 
Any help with additional questions for config selection and then help determine the right keypad, etc for SAP Console?  I’ve heard config makes a big difference with the SAP Console demo experience.
Is anyone doing something simular today?
Any issues with performance?
