      For ultra lowcost Linux systems you can't beat personal Wifi routers
      reflashed with OpenWRT. The obvious major advantage to this over the
      MX233 is the addition of Wifi that includes FCC/CE.

      For example the TL-WR703 from TP-Link. It has 150Mb Wifi, USB and Ethernet.

      $24 Q1 shipped anywhere, about $16 FOB China
      http://www.applehour.com/TP-LINK-TL-WR703N-150M-WiFi-3G--Wireless-Router-for-iPhone-4-4S-iPad-iPod-MacBook--0212-015-

      OpenWRT instructions.
      http://wiki.openwrt.org/toh/tp-link/tl-wr703n

      BOM for these are under $9. You can achieve the same pricing with
      Realtek and Ralink. Note the $16 includes a power supply, Ethernet
      cable, USB cable and packaging. TPLink makes these like jellybeans in
      a factory running 24/7. Millions are sold into China as personal
      routers between 3G and Wifi.

      A good product that is not in the market would be to make a PCB just
      like the TL-WR703 but then route the other peripherals over to an edge
      connector. All of these chips have UART, SPI, I2S, I2C, etc but you
      can't get to them which ruins these boards as a SOM.

      The idea is that the edge connector is almost free. TP-Link could ship
      the same PCB in their high volume routers. Olimex could buy big lots
      and resell them into the OEM market. You also make a bunch of
      peripheral boards to go with them.

          Different applications. Many embedded uses don't need displays. The UI is a webserver on the embedded system. They are also much cheaper than the A13. The CPU chipsets are under $3.00.
