I'm sorry, but you're wrong, and I'm not spreading misinformation. The problem in my girlfriend's macbook cannot be fixed. Apple has admitted this. And the warranty that came with the machine was for 1 year only. It cannot be repaired for free past the warranty timeframe. Additionally, to replace the hard drive under the warranty, the macbook would have to be shipped to California, not fixed in a store in one day. This method would also cost more because of Apple's inflated costs. Instead, she has it repaired by a family friend who replaces the hard drive for her for much cheaper. Still, she loses all of her data that isn't backed up elsewhere, and the hard drive will inevitably crash again because of the fact that the macbook itself cannot be repaired.
It's important that people shopping for computers understand that Apple products are not foolproof investments as it seems you have been led to believe.
Sorry, I'm not trying to flame or anything but like I said, your claim that Apple computers can not be repaired is untrue, except in the case of a MacBook Air. Even you just said your girlfriend's MB was repaired. Anyone with some minimal technical skill can open up a Mac, there are guides online on how to open up a MacBook and replace a HDD. Or you can take it to an Apple Authorized Repair agent or just a random computer shop.
Plus like I said, if you get AppleCare then you have a 3 year warranty. That is no different than a Dell or HP. You get a 1 year warranty and if you want more you buy more.
In the ends, HDDs fail on ALL computers over time... so get an SSD and backup or if you have an HDD backup and then backup again. No matter what system you have.
