In retail and hospitality the hardware is not a back office concern, it is standing between your staff and the customer. When a printer will not pair or a drawer does not open, the queue sees it happen.
That changes what matters. A warehouse device is judged on whether it survives five years of abuse. A counter is judged on whether it works first time, every time, at the busiest hour of the week, in front of someone waiting to pay.
Most of the pain in this category is not about durability at all. It is interface mismatches, a printer that cannot pair with an iPad because it is not MFi certified, a drawer cable wired for the wrong printer brand, or a scanner that cannot read the loyalty code on a customer's phone.
Almost every avoidable support call in retail hardware traces back to a connection decision made at order time.
