Apple’s product lines used to be pretty straight forward. Each category only had a few of each type of product because Apple was really good at making products that fit the needs of a lot of people. That’s changed a little bit.

I think that product line differentiation is one Apple’s major changes post Steve Jobs. Over all I think this strategy is a net positive. More and more of our lives are dictated by technology, and people need more specific devices that fit their specific needs. But this strategy only works if each part of the product line is given the attention it needs. This is evident in the fact that half of the Mac line hasn’t received a major update in several years. The Mac Pro hasn’t been updated since 2013. They introduced a new design and then never touched it in 4 years.
