i've owned a zen micro, its a neat player with good features. fm tuner was overwhelmingly weak outdoors when i was listening to a radio station located just 2 miles away. a radio station which can transmit signals for 150 miles on a good fm tuner. battery is also on the downside. at most its 8 hours. the touchpad face drains way too much battery even with eq, backlight, and smartvolume off recorded at 128 kbps Constant bit rate mp3. its nearly impossible to operate in the pocket, even worse, there is the potential that the headphone jack breaks due to pressure and stress on the jack from the headphone plug.
i decided to get a rio carbon instead. 20 hour battery life for only 170.99. -20$ rebate equals 150.99 all in all. but i decided to get warranty for 20$, so there goes my rebate, lol.
the micro is 229 plus 30-50$ extra battery =250-270 for some people. way too expensive. it has more potential problems than the carbon.
i'm glad i returned my micro to amazon.com, and still received a 30 dollar gift certificate for it. man i am so lucky.
