I am thinking about pulling the trigger on this BT headset- Amazon.com: Plantronics M50 - Bluetooth Headset - Retail Packaging - Black: Cell Phones & Accessories It has solid reviews and current promotion gets you $15 bucks of free music which I would probably be spending over the next few months anyway. . or at least that is how I will justify it. I am also thinking about buying the extended battery. . just wish I didn't already have an otterbox case that fits my current standard battery. Any thoughts?
