For audiobooks to get (almost) out of this one button.
Therefore, I do not mind the small screen (25x8mm) and the rather cumbersome folder navigation.
The transmission rate could be better, but is acceptable. The transfer an audiobook with approximately 70MB (or 70 minutes) takes 120 seconds. The same audio book takes just 20 seconds when I copy it to a USB 2.0 flash drive.
Conclusion: for audiobooks and podcasts ideal - who studied the menu for a title, should have good eyes
