It seems like something that will get lost after 2 seconds since its so small. Wouldn't it of been better if they made something really slim that just attached to the bottom of your phone? So if you did want to regularly charge with micro usb, you could just leave it on and not loose it. The other thing I don't get is why Apple charge so much for this tiny thing. In 2 seconds flat we'll see clones of it coming on ebay for $1, if Apple actually priced it at $5 or something, people would actually buy it and Apple would still make a 1000% mark up on it.
