Otherwise, the Cowon quality is there, you will discover another world if you come from an ipod or other nonsense like that, or if you listen to the mp3 in general. FLAC or OGG sound on a cowon is hearing slap. I will not spread myself on that, for me the criterion of the memory capacity by taking into account the audio quality (because with 16GB memory with FLAC you will not go far ..), c 'is the best of the market.
Let's talk about what angers now: the interface. It's a little scary, it bug time to time, but eventually you get used to. It is time to retain an Cowon android more "pure" that better, more stable, with the processor that is fine. Because the bugs in his recurring Cowon is unfortunately quite known, that lag a little. Too bad, because the quality is there.
In short, if you are an audiophile, go.
