I thinking mostly in terms of space and cost. Some PC USB components are very small. As small as a wireless mouse nano adapter. The best it appears that Microchip does is G in the 2.4GHz range. Many of these cheap adapters can do dual band N(2.4Ghz + 5GHz). I realize that USB full speed can't do G speed, but the lower Wifi speed will slow down access points I would think.
Does Microchip actually give out the SPI protocol for the Wifi modules? The last I looked it wasn't in the documentation and the only real reference is the TCP/IP stack source code.
