My Mum, brother, 2 Aunties, SIL and MIL all have the Nespresso DeLonghi Citiz machine. Very simple to use and barely any bits to clean. You can get it with or without the milk frother. Just pop the pod in the top and press the button for either a short or tall coffee. Too easy! If you go for one without the milk frother/warmer, then your DH would just make his coffee by warming his mug of milk in the microwave first, and then add the shot off coffee to it. It just won't have the foamy bit on top.
