I haven't bought an iP5 (and I'm quite happy to wait for the next iteration), but I must say... what's wrong with some of you?
I've owned *a lot* of Apple products, and the one thing I've learnt is: there is no such thing as a perfect iThing. Seriously. You may think you're paying astro-bucks for your latest device, but unless you've ordered something hand-made (like a fine boutique guitar amp, or a piece of exquisite jewellery), you're going to get something made in a Chinese factory. Not painstakingly put together in a white room by smiling Apple employees - a fast-as-machinely-possible construction from Foxconn. Of course, there are standards to be met, but if you're all Apple fans, you'll know that almost certainly Apple has rushed to meet expected demand. Like last year. And the year before that. And so on.
I bought an iPad 3 yesterday. Funny day, I know, but it was the last day of the Back To School promo, I had found a buyer for my iPad 1, and the wife gave the green light. Happy days, especially when the wonderful young lady assisting me threw in two free Earpods in addition to my discount and gift card. But anyway, first thing: I checked it in the store for cosmetic defects. This is a no-brainer. I got home, and did the magnifying glass thing - a couple of small 'birthmarks' in the metal (not dents, just discolourations). And you know what? I was very, very, happy. Someone else might have returned to the store, but I know very well that a replacement may actually have something wrong with it. Too long / didn't read: minor cosmetic blemishes are to be expected. It's an iPhone made in China. The magnifying glass hunt for imperfections is such a 1st-world problem, it's actually shameful.
Of course, a huge dent or a nasty scratch is not good. I certainly would take it back. BUT, having worked for a major telco many years ago and supporting previous iPhone launches from a customer services point of view, there will always be that one demanding guy who feels the need to go through 5, 10 iPhones on the hunt for the elusive unicorn-built 'iOne'. It doesn't exist. Don't be that guy, people, don't be 'that guy'.
Love and hugs. Hope everyone gets the iPhone 5 they want.
