I really like this product, but there are a couple problems.  Where do you carry it, do you leave it plugged in?  If you plug and unplug say, daily, you'll wear out the connection on the phone.  Realistically, there should be a cell phone made to look like this, with a handy-dandy clip on the top for your belt loop.  Or, maybe a wireless model, like a Bluetooth.  Lastly and unfortunately, there's the doofus factor.  I'm wearing my cell on my belt, my Novophone on another loop, there is a wire loop falling aroung mid-thigh, and I unsnap, hold it to my ear, and say, "Hello."  At this point, it looks like just another nerd gadget.  It works well, but I'm afraid it's one of those inventions that just didn't make it.  If someone makes a cell that looks like this, it's mine in a heartbeat, but until then, to the garage sale.
