Maybe the biggest thing to remember is that Project Ara is only as good as the modules available for it. Thankfully, the ATAP team still has a considerable number of partners either interested in, or actively developing, such smartphone add-ons. The list for now includes E Ink (for tiny secondary displays), Toshiba (maybe for additional storage?), Gotenna (for potential off-the-grid communications) and Sony Pictures Home Entertainment (for God knows what). Alas, developers who sign up for their pre-release kits might not get to play with many of these -- we're told the dev units only ship with a few modules.
