Fair enough. I'm just saying that a kneejerk "use firefox!" doesn't necessarily help: it isn't that simple.
Whether you should really need so much computing power just run a web browser is a different matter entirely. My cell phone probably has more processing power (and definitely has far more memory and storage) than my desktop computer did when I was in high school.
