Spots on the screen?
Are you a smoker?
Hmmm .... Last year,I took my 3 year old iMac ( 24" ) in to have an HDD issue looked at. A tech came out and ran a test and confirmed the HDD was going bad. They said to leave it and they would repair it as soon as possible.
I got the call and went back to pick it up.
At that point they informed me that because of Apple Care I had saved myself something like $1400 in repair bills. I was like....
$1400 to replace the HDD????
The employee said, " oh no, we also replaced your LCD panel because the tech saw some spots or something and .... "
They never called to ask if I was a smoker but AFTER they had repaired the unit they asked that question.
I am using that 24" iMac as I am typing and it never looked better.
Because my Apple Care on it expired just this week, I am looking at a new one. Probably a 27" I7 version, oh and you can bet I will be buying the Apple Care for it.
