okay, i've had a tough time between the carbon and micro also, a tough time in deciding that is.
i owned a micro, i dont know why i returned it, i guess the bad headphone jack problems users complained of scared me.
amazon refunded me through amazon.com store credit.
1 month later, the carbon's price is only 179.99-20$ rebate= 159.99
i just placed and order for the carbon today, using the standard shipping of 5.85 (hopefully amazon gets it to me fast).
the micro right now is 229.99 on amazon.com. by buying the carbon, i save 65$(plus shipping). granted the carbon doesnt have replaceable battery, or fm radio, or on the fly play list or delete. but 159.99 is a good deal that is so hard to pass by.
the micro i think is also pretty damn great and awesome. hell, i might change my mind and cancel the order to get a micro. i'm way too impulsive.
so go for the carbon, lets buy it together.
