Darth, while everything you say is true, I could use those same type of arguments to assert that nobody needs a $3000+ bike when a $500 bike will do the same job. While nobody needs them, a lot of people get them and enjoy them. (That refers to both the $3000+ bikes and the velos.)

Nobody needs a $10,000 boat, either; based on my opinion anyway. I bet if I posted that opinion in a boater forum, I'd get a lot of responses. A couple of them might even agree.
