I am not sure I agree with your statement, Carsten. After all, what is the difference between going out with a fixed-lens prime camera, or with an interchangeable-lens camera where you only mount the same prime all the time? One is simpler than the other, yet the result is the same.
For example, today I am carrying the ZF.2 35/1.4 and 85/1.4. I will probably only use the 35, but I might use the 85. I am not sure that answers your question though.
In essence, I don't value small that much. I am not a huge and strong guy, but carrying a 1.5 kg load (camera with lens) is the least of my worries. If the camera was cheaper, I could justify it in my mind as being for a single purpose, although the wealth of buttons and menu items contradicts this, but at this price, it just makes more sense to me to choose between my D800 and E-PL3 (soon to be E-PL5), depending on the situation. In fact, I find small cameras annoying to operate, often, The E-PL3 is okay, because it has relatively few buttons, and the Olympus menu system is very good at being set up once and forgotten. The other thing is that every time I switch from one camera to another, I am working against being completely fluid with one. Something always carries over from one camera to the other in the mind. Adding an RX1 would give me a third system, but it would not enable me to ditch either of my existing systems, just adding to the disconnect.
