Depends how much you like the Aol interface and its way of doing things.
I have used nothing else for years and will only change if Aol continues to chop free advice and reduce some of the frills it used to have. As it is, I'll stay with Aol.
Two important things if you decide to stay.
(1) Scrap McAfee. There is better stuff available for free and regularly updated.
(2) If you are happy with Silver, don't upgrade unless you are ready to be locked in to a new year's contract.
