I need to purchase around 10 tablets or laptops to enable very technically challenged users to open powerpoint presentations and videos that I copy manually onto the device. The following restrictions will apply to the device- no network connectivity allowed- no copying of content to or from the device via hardware portsOnly I as sysadmin will be able to unlock those restrictions with the device physically with me.The device needs to be able to connect to a variety of old and new projectors using HDMI or VGA.The device needs a screen that the presenter can see I am currently considering: - Android device that has VGA and HDMI ports or adapters for them- iPad with VGA and HDMI port adapters- windows laptops running Windows enterprise (10 licenses) so I can use Microsoft Applocker to lock down the entire laptop so only Powerpoint and VLC player can be usedFirstly what would you recommend from the above options - cost is sensitive here.Second are there any better options I should consider?
