When I purchased my cell phone last year, I must admit that one of the things I was influenced by was the manufacturer's slogan. The phone that I ended up choosing was an HTC Eris, whose slogan is "quietly brilliant." I love it. I don't know what they intended by that message, but I like to think that it suits me well.
It's funny how much of a role personality can play in product choice. I wonder how many other introverts were swayed by such slogans.
