I'll address your points backwards-like.
I don't know how much clearer of a contradiction you can make; on the one hand you say the lens is useless, on the other you admit it has uses. That said, I completely agree that the lens is a waste of time (as far as using it; we can talk for days...)
Yes, I'm 16; Yes, I have a D70, D300, and a Mac Pro. I assume you "hmmm" either translates to "wow, you're spoiled" or "bulls**t". I don't deny that's a lot for a 16yo to have, however my mini-business makes some on the side (granted, not close to enough to cover all that). What I think makes me not-so-spoiled (prob. is it's a societal definition) is that I use each and am grateful.
Oh, and if I translate the "hmmm" as "spoiled": I despise people passing judgment on me before they know me. Knowing me through the forums doesn't even come close to knowing me--the whole internet disconnect. So please just **** and get back on topic (which isn't me).
