Most people draw a distinction between a phone/tablet vs a desktop/laptop. It's not a distinction that can be easily defined, but most people instinctively categorize them as such.

But regardless, the issue at hand has nothing to do with that definition. The discovery process requires them to process any applicable devices that might have info, potentially including all of the above (and more). His team said they already did his phone, but that the laptop in question is not used by him. His opponents say that he has not complied with the requirements of discovery.

The judge will rule on whether that laptop is included in the discovery order.

A particularly fancy drainage pipe is a computer. I think its reasonable to make the distinction that a phone /= computer for the sake of normal definitions.
