   I'd say you're absolutely correct.  Still, that gives you 500mbps   
   transfer speed. I'm not really claiming it will even do that, I'm sure   
   there's processor overhead and whatnot, but I suspect that one could do   
   some number > than 100 mbps.

   I can believe that.  So if we assume these scale linearly, then a router   
   advertising 1000 mbps should, theoretically, be able to transfer from pc   
   to pc at 200 mbps which would be double the ethernet port.

   Of that I have no doubt. There are many factors that affect wireless   
   transmissions, but nevertheless my only point was that a router with a   
   100 mbps port can still transfer data faster than 100mbps. Yeah, it   
   would make a whole hell of a lot more sense to have a 1000mbps ethernet   
   port, but it's not an isolated case.   
      
   Ubiquiti pulled that crap with nearly every M series device they ever   
   sold (with a few exceptions).  Using a 40MHz signal, one could get a   
   300mbps connection, the system was full duplex which gives you a 150   
   mbps connection in both directions.  But since the radios had to connect   
   to the rest of the network with the ethernet port, the 100mbps port was   
   a significant bottleneck.

   Agreed
