Taking the thread late...
What's cool is that they even use "modern" chips with a hacker friendly
package (i.e non BGA) :
This one features a SoC containing a Cortex-A8 @1 GHz but with a
friendly eLQFP176 package
But before buying this kind of chip, you need to take care of checking
which pins are actually bond to the package so that you make sure you
have all the feature you need available. Check for pin muxing as well,
if you need feature A and B but both are pin muxed to the same pin it
can get really tricky...
