Apparently polite discussion is beyond you. Don't worry, you'll grow into it. Maybe . . .
When you work in an area that requires both wired ethernet and burning discs to transfer data, the loss of the optical drive and the price increase, combined with a performance increase that will be invisible to the overwhelming majority of buyers, the new iMac is a step backwards.
I, personally, don't care how thin it is. But when form takes precedence over function, as is the case here (and with the rMBP, the MBA, and the Mac Mini), I question the long term viability of the proponent. If you can't see the tradeoff, and recognize the potential danger, then you should go back to whatever online class you're taking and get a refund.
Finally, I'd bet I've been using Macs longer than you've been alive. Just sayin' . . .
