Hi All, My apologies if this question has already been asked, didnt have much time to check but hoping some people have had any experience or knows about this issue at all. I have a friend who used to work at apple and she had said that the aluminum Imacs are known for having issues with moisture causing issues with their screens the other is dust and overheating issues. Now granted these issues are actually detrimental to any computer component but, I was curious to know if this is especially and issue with Imacs or if people have had previous issues already. I plan to get a new mac within the next week or so. Big purchase which would be pretty price. Also how does the Imac stand in regards to processing power over a quad g5 or a g5 in general. Thanks in advanced.
