My housemate had a "proper" coffee machine and it was ok for one cup, but it temperamental. If I packed it too tight it wouldn't work. I couldn't reliably get the same result.
It is also very hands on. Nespresso machines let me make 2 within a few minutes while I prepare breakfast. Start warming up machine, milk in frother, cup under nozzle, press start.
