I looked also at BlueAnt last night. I wouldn't mind if the life was projected at 10 years, but when they said as short as two years depending on use, that was just too little for me. Having had many cell phone batteries go TU in the 2-3 year time frame, I'm not buying an intercom for that kind of money with a battery type with a 2-3 year lifespan and then have to throw out the entire unit. That is just insane in my opinion, but apparently enough people are buying them to keep the makers in business.
