I plan on getting hold of one of these which I found while researching stuff for the Raspberry PI which I may never get hold of waiting waiting waiting.........
The MK802 supposedly will boot any Standard Linux OS - I will be running one of the PuppyLinux Flavours:http://puppylinux.org/main/Overview%20a ... tarted.htm
flavour not sure which yet with XBMC on it or maybe just straight XBMC.
Go have a look see what you think, there is a 512ram one as well for around $60 bucks. http://www.geek.com/articles/chips/74-m ... -20120517/
Re the Raspberry there is going to be a specific Puppy Linux dedicated to this so it may or may not end up amazing.http://puppylinux.org/wikka/Puppi
There is also this reviews and info for the CX-01 around $53http://liliputing.com/2012/06/cx-01-53- ... stick.html
