Audiovox CDM-9900

I hate to ask this question, but how does the phone compare to the 710 excluding the camera and bluetooth. I have the 9900 and it is a great phone for the price. The camera is ok, but in no way replaces my digi cam, so it's importance is irrelevant. The 9900 can't do vibrate/ring, which is kind of an annoyance. The speaker phone is ok. Charger port is awesome compared to moto. With NE2, is the 710 worth the extra $100 with it's advanced voice recognition and better speaker phone..etc.?

Just wondering...thanks in advance.
