Apple products need just as many repairs as any other reputable brand of computer. The only difference is that Apple's service channels are a little more convenient than some. I'm an Apple tech by trade, and I had a good chuckle at this.
I work for an Apple repair center, and one of my clients has an Xserve currently awaiting a replacement logic board. The machine is supposed to be covered by an Apple 4-hour Silver on-site service agreement, however it's now 24 hours later and I'm still waiting for Apple to dispatch the replacement parts. Nobody internally can provide me with any information other than "we're looking into it".
Their business is extremely limited until this Xserve is repaired. I wouldn't be surprised if that client no longer purchased Apple hardware, and at this stage, I really can't blame them.
Also, for what it's worth, the memory modules installed by Apple into their product range are standard Hynix modules. There's nothing special about them, they don't have any Apple branding and the part numbers on the chips are the equivalent to your typical off-the-shelf standard notebook memory. Remember, it's the Intel chipset that the memory has to interface with. There's nothing special about a Mac Logic Board that necessitates the need for special memory and Apple certainly doesn't supply special memory, they just charge a premium to have it installed out of the box.
