The last few weeks have been a PITA, 2 of the 3 iMac's we own are going down!?!?! My sister's 20" iMac, had it for just over 3 years is dying. I was told by Apple that the Case Logic Board needs to be replace which will cost $900+. It doesn't make sense when you can just buy a new one. Now my brother's 17", had it for lover 2 years is acting up and I think it's just the HDD? I have an appointment with Genius Bar later this afternoon. I'm aware things fail but when you pay $300, $500 more for Apple, as my sister said she just expects it to outlast her Dell PC/Windows she bought 7 years ago! They are questioning if they should get another iMac. What's sad is my sister was thinking about buying the new 13" MacBook Pro before all this. Just had to get this rant out because I convinced them to switch and spend the money to upgrade/buy one.
