I'm wondering if having them "side by side" (figuratively) would serve users of both models. That is, a searcher clicking the link for either in the "Android Phones" area (or a link presented to them by a Staffer in Intros or AL, etc) would lead them to a page with a brief, cleverly worded, explanatory "which model please?" so that they could feel like they're in the right place.
The explanation could also be there in both areas as a red fonted spiel right at the top, or where ever. Staff can keep an eye on the area for kind reminders and thread moving.
