macbooks are not minimalistic in any sense of the word, the concept, it's utilities, etc. Not sure how this would be a part of anyone's minimalistic arsenal.
Apple products have always been minimalistic. Minimalism has nothing to do with being cheap. Minimalism is doing things like removing the floppy disk drive at the turn of the century, carving a laptop out of a single piece of aluminum, or removing all jacks except one or two.
Besides, it doesn't matter. The writer isn't saying that any one of his possessions is minimalistic. He's saying that his number of possessions is minimalistic.
