hi guys, the tech came out on friday and replaced my logic board and one of my four 700GB internal drives. unfortunately, that didn't solve the problem of 2.0 USB peripherals not mounting--including my 1TB backup drive. on the phone with Apple support: they are sending out another logic board and a power supply to be installed on monday.
the tech said that he frequently will replace logic board after logic board in limping computers until he finds one that's stable. after 3 replacements, Apple sends a new machine (if you're under warranty or under Apple Care, that is). the logic board is a complex little number, and i can imagine a lot going wrong, but still, that kind of replacement doesn't strike me as cost effective.
in any case, he did tell me that in his experience, apple manufacturers have been subpar. he mentioned that Apple released a backup drive that was so faulty, that in the end, they had to pull it and re-brand it (they went with a new manufacturer). kind of comical, really. it's a backup drive, after all.
in addition to video, i do research and run processor-intense programs on PCs (Matlab, VBM). i so rarely have a problem with the system, it's not something i would ever even worry about. at all.
i do love Macs and their applications. i suppose that's why i have one and have fault-tolerance built into my backups, and why i have Apple Care, but i am still curious to know the real deal on Mac stability and longevity.
--does anyone know where to get hard stats on Mac stability and longevity?
