Im surprised no one has made the semi-obligitory "buy Ubiquiti Edgerouter X/Lite and throw in a NanoHD" comment.
As someone who recently got the Dream Machine Pro with NanoHD access point, most of the consumers will not want to deal with such a setup. Also, Ubiquiti has their own issues to sort out as well.
I also own a UDM Pro, and this is an understatement.
