Just to clarify - none of us think that Apple buying Beats will make them "cooler". We all buy Beats headphones and Apple products for the same reason we do anything: everyone else is doing it and that makes it cool. Nobody buys Macs for their quality, we just buy them because our parents are usually paying for them and we don't care how much it costs if it's cool. Same thing with Beats. Everyone knows that there's much better quality headphones out there (for much cheaper too), but we don't care about sound quality. Wearing Beats makes you cooler than the guy who's wearing those weird silver, grown-up looking cans that lack a certain letter red letter on the side.
Basically, unless we're footing the bill (and sometimes even then), how well something works is so far down the list of priorities below how cool it is that it's hardly a deciding factor in purchases for us.
