To me, mirrorless means a lot of money for a small camera that is not as comfortable to use nor as fast as a DSLR to focus, and when you want to change something you have to delve into the on-screen menus because the body is too small to have a dedicated button to do so.
It also means paying a lot of money for a lousy choice of lenses and every time you change the lens, that dirt will fall onto the sensor as there is no mirror in front of it to protect it.
There are so many falsehoods here that I don't know where to begin. "Expensive" is relative, but micro 4/3 are in their third generation, so older bodies are available at very modest prices (comparable to P&S prices). The same is true of old Sony NEX bodies. So it's incorrect that the camera is expensive.
"Comfortable" is in the eye of the beholder, but there is a large variety of mirrorless cameras on the market with varying levels of external controls. Panasonic GH2 and Olympus OMD won't require much digging through menus. Even cameras with fewer external controls like the GF2 don't require you to "delve into menus" because the touch screen/Q-Menu system provides very quick access. In practice, changing drive mode (for example) is no harder on a GF2 than it is on a 5D Mark II.
As for the "lousy choice of lenses", that's probably true for some systems (Sony NEX, Nikon 1, and the as yet unreleased Canon system) but less true for micro 4/3.
I reckon a good quality P&S like a Canon G1X is a much better proposition IMHO.
Doesn't that have most of the disadvantages of the interchangeable lens cameras ? Expensive, limited selection of lenses, less egonomic than a DSLR, slower AF ? It's also about the same size as a DSLR. But it's a Canon.
As for "fad" -- mirrorless has been around for a long time (P&S) as has interchangeable lens. So having the two together is almost inevitable. It's probably true however that not all systems will survive. We have Samsung, Fuji, Sony NEX, Samsung, Nikon 1, Canon (if they release it), and Micro 4/3. Not all of them can win.
