ya i dont think ubuntu mobile is complete yet but if there is a prototype version like a beta ubuntu i would try it out.I never heard of KDE ill look into it, its just that for transfering files from the samsung s5 mp3 player would require a windows os. I was thinking of using something like a windows substitute for transfering files on the nokia n810. Thats another reason why im also thinking about getting a palm instead of an n810 becuase of the application compatibility.
