I used to feel the same as you gentleman until I got the MA1 dongle to run wireless AA in my MX-5. The main benefit I see is that the phone never leaves my pocket when entering the vehicle. I get in, sit down, start the car, the phone connects and AA starts running. It may seem trivial but it is a convenience you get used to very quickly.
As for charging, I bought a MagSafe phone case for my Samsung and a MagSafe charger and holder for my phone mount.
My wife loves the wireless ACP in her CX-50. She can put her purse in the front or back seat and go with no need to fumble for the phone and plug it in.
Now that I re-read that, just another fine example of how we* are getting lazier.
