Could everyone who has ever owned an ibook leave their thoughts on whether applecare is necessary? Who has actually taken advantage of their applecare, and what for? I'm a pretty computer savvy person, and I could figure out the OS/software I'm pretty sure. I'm looking more at the hardware/warranty part of the deal. How common are dead pixels or HD failures that only show up after the one year warranty that comes with all ibooks expires? I need to figure out if I want to buy the warranty...$183 is a bit pricey.
