Query: Mot HS850 Bluetooth Headset opinion

I found the Motorola HS850 Bluetooth Headset did not meet my expectations. The link below identifies the device.http://www.amazon.com/gp/product/B0007WWAGI/ref=cm_cr_rev_prod_imgThe product had a shroud on it which I found annoying and after having used the Motorola HS700 Bluetooth Headset for years prior to the purchase of this product I found the power adapter and car adapter lack of compatibility with USB connectors very inconvenient. More and more I find the USB mini-connector charging system is becoming a ubiquitous standard and lack of this compatibility, when I have many other devices using this system makes it cumbersome at best to have to carry around additional car adapters.
