When I'm in my car (Acura TL) I use the Handsfree Link which lets me communicate through the car's speaker system. Nobody can tell the difference between that type of call versus me holding the phone to my ear. I love how I have caller ID on my dashboard and call make outcalling calls using voice recognition. Since it is Bluetooth, it works even if my mobile phone is buried in my briefcase which has been tossed into the back seat of the car.

When I'm not in my car, I use my Motorola RAZR as a normal phone. I refuse to wear a phone as an accessory so I like how it slips into my pants pocket. It's so thin and light so I hardly notice it's there.
