I don't like the marketing appeal to some sort of deep emotional instinct that the advertisement is making. I think it's ridiculous that consumer goods represent who I am and what I might stand for. That's silliness and hyperbole, right? To say that a person's phone choice defines them in any sort of meaningful way is extremely silly to me. This feels similar to something like:

"This product stands for freedom! You stand for freedom don't you?"

The guitar analogy is not accurate - your statement about cherishing the guitar is evaluated internally and is true or false. It's not the same as saying the guitar publicly and externally (and deliberately!) defines you and what you stand for.

"There goes lolsal - now there's a guy that really stands for non-branded personal compute devices!" Give me a break.
