Yes, it is a tool. And sometimes tools differ in boring ways that make no difference, like they have different colors.

But how would you feel if you worked as a carpenter 8+ hr/day for 10 years and then realized you had been using a dull saw the whole time? Or that you were doing things in a slightly wrong way which gave you blisters or split the wood?

You might even want to tell other people about it...

I don't think using an Apple brand computer vs. another brand really makes that much of a difference to anything except taste.
