My company uses several hundred iOS devices for sales and delivery and we are now planning on piloting a warehouse picking system. Our oldest hardware in the field now are iPhone 6. The question though is do we order iPod touches, despite their older hardware? Or do we order refurbished iPhone 6s or SE or potentially 7 and simply not activate the cellular? Storage requirements are minimal so 16 gig phones would be fine. What do you fine folks think?
