This Nokia concept phone is a bit out there, as far as weirdness goes. It’s called Nokia Prism. The execution of the Nokia Prism phone is flawless. This prism-shaped phone looks good only as a piece of art nouveau and only when seen from the back
The problem with the Nokia Prism is that it has those sharp and angular corners and edges, making it not very comfy to hold, actually not comfy at all. Not to mention about the resolution and the fitting of apps on the screen. It appears that the most prominent corner is reserved for the signal and notifications, while the “base” of the phone shows the rest of the UI and video playback screen.
This would work fine as a boomerang, but a phone? … Problematic!
