An hour with Apple's support team
After an hour or more of scrolling and scrolling, it's easy to believe that Apple's devices really aren't too good. Until you remember there are billions of them now out there, somewhere.
Still, there's something instructive in seeing how vast the gamut of issues truly is.
Especially when it's cold.
Sample from a customer: "Why are iPhones so sensitive to cold? Why does @Apple not fix this? My phone battery went flat and the phone shut itself down when I came inside today. It's just -5 Centigrade." More here.
A reasoned summary of what Apple has to deal with.
