I think this kind of case is genius because everybody needs a case on his phone since you need that extra layer of protection nowadays, especially that most of us use their phones all the time. But, most cases only give you protection, and, if you want for example a power bank, you need to carry it supplementary. Also, I find the speaker highly useful too since the quality of the speakers most phones have is not the highest.

I would like to see phones adopting a kind of modular tech in the future too, even if it might come at the expense of their slimness since it’s so useful. But, I get the feeling that the big manufacturers are moving in the opposite direction, taking away more and more things and giving us dongles instead of more features.

Keep on hunting.
