Modular phones (remember that viral Phonebloks video?) seems to be the holy grail of open source technology today. Just imagine, a smartphone whose parts you can upgrade – and not thinking of a whole other phone to purchase when you grow discontent with what you currently own. It’s a change in the paradigm of the smartphone industry. This is why Google’s Project Ara is a big deal. But it seems they’re not the only ones racing towards a modular smartphone product.
