Yes, having coffee on the train is a preference, which is why I used the word "want". I suppose that having this job, or any job, is technically a preference. I decided to buy a smart kettle to satisfy my preferences given the constraints they impose. The parent asked why someone would buy a smart coffee device, and I thought it would be fun to give my answer for why, despite my general skepticism of smart devices, I bought one.
