Then take the EP9302 and add:

Previous cost:                $27.74
SD Socket:                    $3.80
SD 128Meg card:               $8.00
64Mb (4Mx16) SDRAM            -$5.67
32MByte (16Mx16) SDRAM        $12.54   Total: $46.41

And you get a killer Linux powered embedded system!

BTW, where did you find the cost of the EP9302?  I cannot seem to find 
anyone but Cirrus that you can get those parts from (e.g. Nu-Horizons, 
etc.).
