Swissair used Nespresso circa 20 years ago -- so there has been lots of experience with Nespresso inflight. It works great and removes the skill element, also it is unattended. Perfect application of the technology (as it is for hotel rooms). Consistent quality with no effort. For home use these aren't such important factors (I generally use a hand-operated espresso maker, and sometimes even a stove-top Atomic for sufficiently important occasions, because I like the ritual of making the espresso by hand and serving my guests with my skill rather than pressing a button).
