So I got the Plantronics headset. It's great!
Being very small, it has a holster that it fits into, which fits into my shirt pocket with a clip (and sits right next to my pen in my pocket). Even better, it vibrates when a call comes in, and when I pull it out of the holster, it answers the phone! YOWSER! To hang up, I put it back into the holster! SUPERB!
Unlike the Motorola, it doesn't turn off when charging, so it's always on and available. Plus I don't have that dorky Motorola bulge in my pants pocket where I would carry it (that was so that I didn't look like a goofball walking around with it on my ear all the time).....
