I'm looking for something in the $70 price range and after looking through various reviews I have gotten down to these three devices. The miniblue is the very small piece that is simply an earbud...this looks the best but my only concern would be performance. I have heard mixed reviews on all four devices, so I was looking for a first-hand account from a MacRumors member. Of course, this is going on my new iPhone 3G so keep that in mind. Thanks!
