I wonder what is the actual addressable market size. For example I know my needs are very well covered by Nespresso as my main requirements are fast brewing, easy manipulation, no washing necessary. Maybe there would be a way to convert people like me (and I suppose we are in majority) to something fancier? I currently pay around 0.40€ per dose but I would be prepared to pay a bit more.
