Hello, I am brand new to the forum. Just picked up my brand new 21.5 imac today (my first imac btw) I have the 13" macbookpro and I'm moving away from a dell to this imac. 2 questions, and one comment. #1 - I believe I have a dead pixel, but need some confirmation on this. It looks as if there is a spot on the screen towards the bottom left corner. Almost like something was on the screen, but wiping it with the cloth still shows it's there. I see it when I set my background to any solid color other than the dark gray they give you. Is that a dead pixel? #2 - My serial number starts with W8953 so according to what I've been reading here that means my mac was built in 2009 in week 53??? Obviously that can't be right. So, what week would it have been built in? As for the yellow tinge. Not sure... I think all the talk here has made me think it's yellow, but it may just be I've been staring at it for too long. It it the screen that looks yellow or the gray bar gets a yellow tinge to it? OOPs, that's actually 3 questions. Thanks for any answers/help. I was really looking forward to a great experience. After dealing with a dell for 3 years I need a good uncomplicated experience.
