I purchased a refurbished Mid-2009 MacBook Pro from Apple.com last week and the unit I received has a yellow tint plaguing the bottom 1/6th of the screen. Truth be told, it doesn't and probably never will really affect my work but it is really annoying and it seems unacceptable for a computer of this price. I have an appointment with a genius this evening but was just curious to see what kind of luck people have had with defects of this nature. I've only ever had to deal with Apple on larger, more pressing computer issues. Thanks.
