Holy Bulging Capacitors!
Last month my computer started turning itself off or not even turning on. Before that I had experienced a strange phenomenon where my cursor would move to the corners of my screen by itself. Well it turns out that I'm a victim of bulging capacitors which is an industry wide problem. Luckily mine iMac was covered under an Apple repair extension program at no cost to me.
I dropped my computer off at the Apple Store on a Saturday afternoon and they told me it might be 2-3 days before it was ready. While I was worried about how far I would get behind on work, I was actually excited about how much other work I would get done (e.g. organizing my desk and life). Alas, I got a call that evening that my computer was ready and I picked it up that night to avoid weekend traffic at the mall on Sunday.
