Yes, I have brand fidelity, and when Randal mentioned Apple, I could not resist! When Steve Jobs returned to Apple and turned the company around, it delighted me greatly. I have been using MacIntosh computers since 1991, and love them.
When I was a kid, my mother knew that I wanted Levi jeans and I was happy, and that is still true. I do not know that I have ever worn any other brand, and I am 53 years old!
