Apple Care Efficiency When Macs Break?

cyber-dragon.net asks: "I have long been a staunch supporter of Apple and Macs, however my recent experience with trying to bring them into my department, at work, has been disappointing. We had a Mac Pro (the big quad processor monster) die after four days. Of course, this kind of stuff happens, and everything else has worked flawlessly. I even dealt with the inevitable teasing about the shiny new Mac being a lemon. Almost four hours dealing with Apple Care, three hours dropping off and picking up my computer at different stores, as per their instructions, trying to get this done quickly — I am beginning to wonder if Apple really wants business customers to rely on these machines. Much as I may dislike Dell, when my Linux box died it was fixed in four hours, and I spent maybe 20 minutes of my time setting up the repair. I have spent seven hours of my time so far on this Mac, and it still will not power up. Is this just me or have other people lost critical business machines to the depths of Apple Care inefficiency and lack of business level support?"
