The jaded geek in me says just run some ethernet this WiFi is too much hassle

Yeah, but lots of devices people might want to use on their home network are inconvenient to tie to ethernet. There's a good case to be made to wiring what can be wired, though.

The consumer and frugal shopper in me sees the $400 price point, and doesn't think it compares favorable with a few dollars worth of aluminum foil.

Beware cheaping out on wifi kit I have bitter experiance of trying to use POS dlink kit to provide wifi in our new office.

But for home use multiple AP's with powerline to connect them is actualy a simpler solution than mesh as using wifi for the DS (distribution system ) is always going to be slower than a wired.

I agree, and I have multiple through a wired back end, but due to very congested spectrum usage in my neighborhood, I I have less than stellar reception at certain times in my home office (a walk in closet with no physical network hookups) which is about 30 feet over and up a floor from the closest AP. A little coaxing of the waves might go a long way for me.
