The Nexus 6 arrived at an interesting transition period for Google's stock Android phone program. The Motorola-made device was Google’s largest phone to date, and the company decided not to include a 5-inch version last year that would act as a successor to the popular Nexus 5. That left the Nexus 6 in the odd position of catering to the select few smartphone customers comfortable with a phablet of that size. And until September, it was also the only device capable of running Google's experimental Project Fi mobile internet service. Now Fi works with both the 5X and 6P, so there's no reason to keep the Nexus 6 around anymore.
