I was reading an article about diamond and cubic zirconium earlier on today. Apparently diamonds were originally prized for their beauty and this is in part where their great cost came from. But there is a scientific argument that cubic zirconium is more beautiful than diamond, yet diamond remains far more expensive. It made me wonder about Apple products. I'm slavishly loyal to Apple. I joke to my friends that I'm addicted to Apple products -- except I'm not entirely sure I'm joking. This year I spent over £2,000 on a new laptop. That's a huge amount of money. I think that's more than I've ever spent on any single thing other than my car. Yet I didn't consider any other options. It was Apple or nothing. And the new MacBook Pro was, er, new. So I had to have it. Many people on these forums criticised the new MacBook. I ignored them. How do you know that your Apple products are the best in their class?
