The diagonal size is impressively small, but it’s crazy thick. It’s more than 1.8cm thick! In their images it’s nearly as thick as a roll of film which is just absurd. I’d love a small phone and I’m willing to compromise a bit on it being thicker than the average iPhone, but this thing looks insane.
For a small device like this, I don’t think I’d want it to be thinner. Thick and rounded like this just seems like it would be the most comfortable design for using with one hand.
