Right, and you reckon they'll keep it to this one thread and not take other threads OT? Somehow I seriously doubt it.
Delete this thread and ban the pair of them for six months. If they re-register, or use any other account within that time, ban those accounts and their originals for good.
Apple fanboy or not, I am seriously fed up with both of them from polluting threads, trolling each other. Don't give me the whole "it's an opinion" bollocks, I think we all know it's not and it really is a game of trying to one-up each other. It's not big, hard or clever and the pair of you should know far, far better.
