I was kind of embarrassed to admit we had one for the trailer, but since you asked...
We have a Nespresso machine for the house that we absolutely love, and when they came out with the Pixie, it took me a month before I went and got it. It fits on the shelf in the galley with the hatch closed (I have to take the drip tray off, but it takes seconds to put back on).

They are a bit pricey (just under $250), but we have more than made up for the cost in what we are saving in not having visited a coffee shop in 2 years (Mick sometimes has 3 cups of coffee in the morning and I like lattes, so you can see how that would add up!). Outside of beer, folks in our region love their coffee (we can be a little snobby about it, I suppose). I will say, that if you love frothed milk (either warm or cold), get the Aeroccino. It is absolutely amazing! Like I said, I use it for lattes, but you can warm milk to help you sleep or for hot cocoa, or whatever your heart desires. And it will froth it cold too. It takes less than 90 seconds for it to heat and froth the milk. You can have a latte in less than 1.5 minutes using the coffee machine and the Aeroccino.
One thing with this brand, it is strictly coffee, so if you are wanting to make tea or hot cocoa or other drinks, it isn't going to be something that will work for you (I know some single serve makers give you that option). They do have different varieties of coffee (with varying strengths, both decaf and fully-leaded). Each cup ranges in price from $0.55-$0.65/cup. And we REALLY like the coffee. We tried doing the French press thing over the weekend too, and found ourselves missing our regular coffee (gave us a chance to try out the generator one morning).
The Pixie pulls just under 1200 watts (1160w), which works fine (if I remember right, you can pull a max of 1600 watts). The Aeroccino pulls 400.
I always joke with Mick that this has taken us from camping to 'glamping'!
I will post a picture tomorrow. For some reason, my FTP has lost all of the login info, and I need Mick to log me back in.
