It seems like a great system. Just turn off paypal now and enjoy. I have been paypal free for 10 days now, and no slowdown of sales. I actually had a person today try DC for the first time today, as she had only been a paypal buyer in the past. She loved it and told me, it will be here prefered way to pay in the future.
It seems human nature to resist change, but once you get used to a new system, it usually works quite well.
