Optical Drive will never be dropped...
Although it would be nice if it was.
Never say "never." After all, they dropped the floppy disk drive.
What is the point of a sleep light?
Sounds terrible for those of us who have computers in the bedroom.
My office lights up like a Christmas tree at night with all the indicator lights in the room! One more wouldn't be noticed. The sleep light helps detect sleeping issues and provides an indication of whether the computer is off, sleeping, or just powering off the display. My iMac is so quiet it's hard to tell the difference.
After taking my iMac apart twice its evident how much room the superdrive is taking up. If removed they could fit in more powerful hardware and allow it more cooling room. Perhaps the 21" could have the same top end graphics as the 27" does now (or a lot closer to it anyway). With the extra internal space they could maybe give the internals a bit of a work over and have the hard drive user serviceable. That would be awesome. Its a pain in the butt having to go through the screen for everything (apart from RAM). For those who still need an DVD drive then you can easily sit an external on the base of the iMac or next to it, like we do with external hard drives
They could go that route, but more likely would just reduce the depth of the housing to make it more sleek. Frankly, if they made the housing 6 inches deep to give plenty of room I'd be fine with that. I don't need an anorexic computer!
Actually, even though I need a DVD drive (at least one in the house) I really wouldn't mind if it were external. The current design is awkward to access and frequently scratches (and ruins) the media. It also prevents putting a second monitor to the right. I've got to put it on the left to get access to the drive.
