It looks cheaper than the Wandboard? http://radxa.com/specification/
Does look neat and yes, does appear to be cheaper. Might take a punt on one actually, see if it cuts the mustard. Thanks for pointing it out.
The RK* thingies are fairly cheap, indeed, but I managed to brick one with a simple "dd" from Android and still haven't managed to unbrick it.
From that point of view the Allwinner ones are very friendly (since you
can boot from uSD even with a completely broken nand flash).
