Crap, my Macbook Pro consistently runs into the 70c area and even higher regularly. I added SMC fan controller which helped (I figure it's much cheaper to replace the power supply/fans than the logic board. Plus, my last logic board failure, while covered by AppleCare, resulted in the loss of my MacBook for 6 days because the logic boards were on back order (that's got to mean something).
I still feel that something is wrong because the spinning rainbow ball is almost a permanent fixture on my screen for 10 seconds or more at a time virtually everytime I do something with iTunes, Pages, and other programs. It's only tolerable because I came from Windows Vista, so my performance expectations were so low. Still, my TimeCapsule seems to be failing after 18 months, my mid 2010 MacBook Pro has experienced, in the 2-1/2 years I've had it, a harddisk failure and a logic board failure. I'm old enough to remember Apple's dark ages when Jobs was gone and have had concerns about buying Apple ever since he became ill.
Let's face it, we pay a premium for Apple because "it just works." But not so much these days. But things are changing. Try finding your audio books purchased from the iTunes on your new iPhone 5. Right now one of my Apple TVs tells me that my iTunes homesharing isn't turned on while my other Apple TV connects with my computer just fine.
You've got a problem with your gpu/logic board, you go to the genius bar a few times and they tell you there is nothing wrong or it's your fault. Then you go on line and find out that 20,000 other people are having the same problem and that Apple has been trying to hide it for 18 months. I finally gave up on the genius bar in favor of Apple certified independent repair facilities. At least there you can get someone to acknowledge that they are aware of the problem rather than standing in front of an Apple employee and realizing that "these aren't the droids you're looking for."
We have a planned replacement of all of our computers over the next 6 months and we've hired a consultant to come in and give us input on switching back to Windows based PCs. I still own a Dell Vostro 17 that has never had any hardware failure. It's only 30 machines so it's not going to have an impact on Apple, but reading these posts, I can see that it's not just my company, it's countless Apple users. And, as advanced as Apple is, the one thing they haven't learned in the digital age is that secrets are becoming impossible to keep. Sometimes it reminds me of a scene in "My Cousin Vinny" where the lawyer is questioning a witness who clearly is uncomfortable answering the question and the lawyer looks at him, points toward the jury, and says: "It's okay, you can say it, they already know."
