To be fair, it is lighter and easier to move around. Granted, this is not a laptop, but sometimes you want to bring your rig with you for whatever reason. I like that the newer iMacs are thin and light.
Internal DVD drive? I haven't seen a DVD in five or six years. Flash drives are cheap, maybe you should migrate your media.
That is literally why I chose a 21" iMac recently. Well-that. And the fact my laptops were becoming rather 'spirited' in a sudden shut-down, constant crash sort of way..not good.
Primary needs in order of importance:
Stability

Stability
And I can pick it up and move it from desk to desk for no other reason than, I want to.
I'm in the market for a couple OEM Apple power cords to make the move from desk to desk just that much easier.
i7 w/4cores, blistering fast storage, a fabulous (imo) new os, plenty of RAM (for me) straight from Apple, and it's fully upgradable.
What's not to like? Perfect product at the perfect time for me so, kudo's to Apple from my viewpoint.
It really is a badass little computer.
