Eric Despite it shrinking down to a more dinky size in recent years, carrying an inhaler is still a real chore. Is it possible to store compressed gas in a more pocket friendly way or has it got to be cylindrical?

🏒 Lucian Marin You can always redesign the enclosure of a cylindrical inhaler to match the design of a pocket friendly Lytro camera. But I guess pharma companies don't have any interest in hiring the best industrial designers.

Eric They sure don't have that interest. The corners of the cap (to keep the mouth piece clean) has 4 pointed edges, if your pocket is tight then it can get pretty uncomfortable!
