 One reason to get routers to market is that they will may have a longer
installed life. Clients come and go, but I only replace my routers when
they break or a new technology comes along. Ideally.

I haven't seen any 802.11ac clients yet, but I have tested and installed
some Apple and Netgear APs, and for add-on NICs I've started to stock
802.11ac.

I've got a Ruckus Wireless ZoneFlex 7982 WAP, myself, which is a 802.11n

 In a busy environment, features like the beam forming and extra antennas
are really going to pay off. It will matter less whether any single client
supports the full bandwidth of the router; in fact, some installations may
not want that! I think of it as backbone. Not a perfect analogy to copper
or fiber, as it really is a shared medium. But it's great to see the
continuing engineering that's going into wireless; from one polarity to
two, from two to spin, wider channels, higher modulation formats and
framing.

I have a building where I can't push 802.11ac down one floor and about 40
feet away. That's what two cinder-block walls will do to you!
