My Sleep/Wake button recently became stuck in a recessed position where it didn't spring all the way up correctly for no reason. I took it to the Apple Genius and they replaced it. (Which was nice because there were scuff marks all over where I accidentally scraped the naked back of the old one pretty bad so no its brand new again.) Apparently the ones they give you aren't refurbished they say. But alarmingly, while I was at the "bar" with two other people, a third person came up and said their Sleep/Wake button was broken as well and they only had it a couple months. Wow. So, I know its not exactly science, but out of the small sample size I experienced, 50% of the issues involved the Sleep/Wake button. Im surprised to see how quiet they are keeping this because clearly, CLEARLY, the quality of the product is secretly going down as they increasingly mass produce this thing. Even an Apple employee Ive known for 4 years admitted to that much. I mean, if my calculations are correct, half of all people in the world will have issues with their button at some time or another. If my sample size is to be believed. Even if its less, its a sign that something is changing.
