Ann. Go with the one you like best and can afford. Its all about taste and pocket really. I know when I buy my next phone I will look at both. These products are changing rapidly. When I bought my iPhone, there was less competition about. When I buy my next smart phone, I will keep an open mind and look closely at whats on offer.
Am I right in saying that they are a similar price now? I just looked on Carphone Warehouse and the Galaxy SIII is over £500 pounds now?
By the way, remember that the iPhone 5 is due out soon....
