Well, there appears to be one bad thing about the Creative Zen Micro and that is that a lot of users are reporting problems developing with the headphone jacks after a couple of months. Mine appears to be starting to have the problem as I sometimes hear some static that at present can be cured by rotating the headphone jack slightly. Not a good sign though.
Also although the product comes with a one year warranty, labor is only free for the first 90 days.
