ahh.. now I follow you.... however, due to the way linuxmce handles the kubuntu packages, updates, etc.., it is recommended that linuxmce be installed on a clean, new kubuntu install... there is a great possibility that packages related to the software already installed on the device would be removed or be unusable...
it would be interesting to see someone take the barebone device they sell and get linuxmce running on it... however, I didn't see a price..
