"Just so we're both completely clear: We've spent most of the week flying to Australia to stand in line to buy a phone we're not sure we're going to get," I say to Kyle Wiens, the CEO of iFixit and the person whose plan this was. It crosses my mind that there is a perfectly good Apple Store three minutes from my office.

We have the order confirmation: One iPhone X, to be sold to us at 9:30 AM at the Castle Towers Apple Store. Still, it is entirely possible that there might not be a phone. It's happened before.
