I will limit myself in my review on comparing the Pixie. For "System Nespresso" was already written enough, either you do not like it or stop. I myself use a Pixie, the Inissia I purchased as a gift. 1. the color looks a little brighter in kind, I would rather call it gray light blue with a touch. 2. the Inissia has a smaller water tank, the not particularly large fails on both machines. The not particularly bother me, and I see this as no great disadvantage in comparison, what bothers me more is 3. The cover plate or -plastik (in Inissia) on which the cups are turned off. Subjectively, I find the sheet of Pixie beautiful, practical disadvantages or differences there but m. E. not. Which reminds me, the shelf at the Inissia from memory a tad less occurs. 4. Disturbing can as already missing when Inissia way for winding the excess cable in the machine to be, the cables are kept quite short but eh. 5. Now this is the feature that I would miss when Inissia most specifically is the water level indicator or warning, if the water in the tank for the next cup is no longer sufficient. The missing in Inissia, so you should keep an eye on the tank before brewing. 6. Another difference lies with the control buttons. The Pixie has 3 of its own on / off switch and 2 for the cup of espresso choice etc. or Lungo. The Inissia does not have a on / off switch, but is by the simultaneous pressing of the two cup dial keys connected that bothers me, because you can inadvertently lead to a further cup of scalding water when the keys may not be at the same time, equally strong suppressed. Is my admittedly not happen, but also have always been paying attention that I catch both buttons. Since my Pixie with the extra key is better.
There is no difference in the noise level, because they accept both nothing and at the coffee quality I could not detect any differences and that is ultimately the most important indeed.
