Take it easy, buddy. Proof? Try google. There was a known problem with the Superdrives around 2009 as well.
And once again, another poster talking down the 2012 who also just happens to own a 2011... The pattern is amusing
You're the one that needs to calm down. You're talking rudely to people here. I also had a 2009 iMac that was replaced by my now 2011 iMac and guess what, the 2009 I had for 3 years had zero problems with the ODD. If you need to tell people to use Google then you're full of it because you can't even back up your own nonsense statements.
Uh, you need to read posts properly, I never once talked down the 2012 iMac but it seems like you're feeling the need to defend your recent purchase because let's face it, while the 2012 iMac is certainly a nice machine there's nothing groundbreaking about it. You sound like you're one of the more recent switchers to Mac. I've been on Mac exclusively since OS 8 so I know when I see Apple doing something seriously groundbreaking and the 2012 iMac just isn't.
I always keep the most recent Macs but why should I give up my 2011 iMac for the 2012? Surely you can't be so blind to the fact there's just not enough of an upgrade.

Let's be clear about this: the 2012 iMac's new design is groundbreaking. It's simply beautiful, and I don't say that very often. The improvement in the GPU offered (680MX) is a huge deal, bigger than I think you realize. That sucker is fast (for real-world application). And there are other lesser improvements (CPU, RAM speed, etc.).
Taking out the ODD gives Apple an easy opportunity to make a slimmer cabinet, an upgraded GPU is always welcome, but as you say, "it's a bigger deal than I realize?" and exactly what seriously big deal, so you can play Windows games? I like the fusion drive and of course a faster processor but at the end of the day, the new iMac is advertised for it's new slim design which puts the customer at more inconvenience since upgrades are not as easy anymore and the ODD is gone requiring legacy users of optical software to buy an external drive. I would hardly call this groundbreaking.
