Every year, it seems like Apple comes out with at least one significant new implementation of technology. The issue is that it isn't always distributed evenly across the company's product line-up. Even devices that seem like they could benefit from Apple's latest and greatest additions often get left out in the cold.
That's particularly frustrating, given that one of Apple's strongest selling points in recent years has been how well all of its technology works together across hardware, software, and services. Bringing that kind of relationship to its devices really emphasizes the idea of the ecosystem being a whole, instead of independent platforms.
