I get up very early - a couple hours before my wife so one cup {quiet} brewing is great. We used a Keurig for a several years. While the pods have a long shelf life, they take a lot of space both storage and disposal. Plus they are expensive.
A couple years ago, we purchased an Aeropress - essentially a French Press for one cup. We also have a small 0.5L electric tea kettle. Much easier to clean than a true French Press, and very compact. We use vacuum bricks of Bustelo Cuban coffee which have an insanely long shelf life and are super easy to store.
If you like very strong European style coffee, and are okay with one cup at a time, or you have space constraints, Aeropress can't be beat.
