Modular smartphones are more of an interesting experiment than a viable product. Be it Phonebloks or Project Ara, modular smartphones are a very cool idea and I can’t wait to see how things progress, but I’d still never get one, and most people feel the same way. We’re all too comfortable with our Galaxies or iPhones. However, a new product known as Nexpaq has a way to bring us the customization of a modular smartphone while still allowing us to retain our current smartphones: a modular smartphone case. Rather than changing the phone itself, you’re just augmenting it. Brilliant.
