For personal use, the simpler and smaller the grinder, the better. True coffee enthusiasts will know the freshness of the bean because the roast date is on the bag. They will frequently alternate between different roast, when one bag is down to the last few grams, or a fresh bag has just rested. They will think about this when they are lying in bed in the morning, which makes a hopper a useless tool.

Make something consistent, easy to clean, easy to service, or solve an already known issue in the process. Displace the air around the beans with an inert gas to seal in freshness. Simplify the process and waste of dialing in the correct grind based not only on the brewing method, but also on how brittle the bean is and the oils present.

I wouldn't add features to a grinder just because it can be connected to the internet, there's a manual effort involved in coffee that might not need to be replaced.

Hmm, interesting points about the hopper and added features. Thanks for sharing!

Any interest in the portability of a grinder? Maybe being able to take it with you camping, or anywhere else without an outlet?
