First thought is weight distribution & stability; thumbs and fingers at the bottom 2-3" of a 9" long top-heavy 300g+ weight seems problematic. They talk about how to hold it in this video [1] but don't address the typing experience.
My guess is you have to grip a bit harder than you normally would to keep it stable, and this may impact the typing speed (vis-a-vis old school BB). Cameras make iPhones pretty top-heavy.
I don't see the weight of this Clicks case, I'd guess it's at least the same density as the iPhone (~32g/in height) so minimum of +70g, and possibly more like +100-120g.

Nevertheless I love the chutzpah of this device.
