Many benefits of Google's modular smartphone initiative, Project Ara, are immediately apparent: financial and waste savings through partial upgradeability rather than replacement, functional customization, individual personalization. But consider also:
  1. The front of the device is just as modular as the back. Someone will make keyboards. Actually, there will probably be several keyboard options. For virtual keyboard haters the long nightmare may finally be over.
  2. By making it possible to build just a single module, the market opens to companies without the capability or desire to manufacture an entire phone. Camera makers can make just camera modules. Speaker makers can make just speakers. Etc.
  3. At last you can make a phone that looks like a Piet Mondrian painting.
