AIO does not have to require an outdated piece of technology. It's pretty much going to be a Cinema Display and a Mac Mini (remember, no ODD) combined. Less clutter.
I'm gonna call you out.
Why dose this matter in a desktop? Why does the current iMac need to be thinner? I would love to keep the ODD or maybe Add a blu ray drive, make it thicker ( think G5 iMacs ), add a full sized GPU and better cooling. I think that would make it a better desktop.
Here's the thing dude, Optical media IS dead. I follow it on a weekly basis. DVD will down billions again this year, and Blu-ray can't even reach 2 billion in sales a year without adding in rental revenue. Retailers have shrunk space devoted to DVDs and Blu-rays. CDs are pretty much non-existant at places like Best Buy. Space is now being devoted to Tablets and cell phones - things that don't use Discs.
Will optial media die off for consumers eventually? Yes. Right now? Not yet.
Blu Ray will still almost sell 2 billion copies, thats still tons of profit for those who make it
Right now, online movies cannot compare to Blu ray.
And there are no other hard copy ways to be as good as DVD/Blu Ray backup/
Optical media getting smaller? Yes. I can see it.
However, until steaming/online content can compete, and until there is a good way to do hard copies. I'm sticking with optical.
The cloud is good for some things. But sensitive data? I think not.

Desktops can get skinnier. Why not? Saves on materials, shipping weight etc. Maybe we might get a lower price? Maybe they will add user-removable second storage drives? More RAM slots? Who knows.
Let me ask you this, why do they need to get thinner?
And look at Apples history, this is Apple. If they remove the ODD, they won't give us more ram, they won't cut the price, and they most likely won't add more storage drives. They'll take the money they save via no ODD and pocket the cashs.
