Kids these days are spoiled by their 4 post rack cabinets...
Rack
does not have to mean a metal cabinet. I have a 19" two post relay rack for my network and server gear at the house. My current RB951 AP is sitting on a shelf 2U below the 48 port patch panel and above the Atom based server. I have good RF coverage with the power turned down to reasonable levels. A CRS is on my personal wish list.
It is also not uncommon to mount something like these in small offices and homes:

A patch panel and a CRS with wifi could be all you need for sites with 24 or fewer wired devices. A unit with rack ears would be more tidy in that type of environment. It's not a deal breaker, we can still wall mount something.
We currently mount 2011s inside the steel cabinets at our tower sites so that we don't have to leave the cabinet open in the rain while we trouble-shoot. With the power set to 8db, it works well enough in our trucks parked within 5 meters of the cabinet, and doesn't interfere with the sectors mounted 20 to 50 meters above.
So, while you may think an AP in
your rack cabinet is a dumb idea, there are a lot of situations where a rack mountable all in one networking device like the CRS can be useful.
The question is: Are there are enough situations where a rackmount CRS with wireless is needed to support the extra cost of MikroTik building, and distributors stocking, that product?
I have about 50 clients where that product would be an excellent fit. Unfortunately, they all upgraded to Gigabit switches 2 years ago and are not unhappy with their Zywall/Linksys/Cisco ASA/NetGear/D-Link routers. So, it's not like I would be placing an order for 50 units tomorrow if the product did exist. I would have bought two units for remote branches of a local health care clinic in the last month, had it existed. We installed the desktop model instead. Not as clean, but it worked.
