The hot new gimmick for smartphone makers in 2016 has definitely been modularity. LG introduced the G5 with its swappable bottoms, Lenovo just launched the Moto Z alongside a range of function-enhancing snap covers, and Google announced plans to bring its Project Ara modular device to market. Each of these ventures runs counter to the established direction of consumer electronics toward greater convergence. I applaud the courage of each company to try something different, but just one look at Microsoft’s new Xbox One S — the latest example of what converged technology can produce — convinces me that modularity is the wrong path to follow.
