A long while ago a few list members purchased a few DE0-Nano FPGA boards. Terasic have just released the DE0-Nano-SoC, an Altera FPGA with a built-in 925MHz dual core ARM CPU, 1GB of RAM, ethernet and (strangely enough) Arduino compatible headers - for US$99. http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=1&No=941&PartNo=1
