Well I'd say return or sell it, buy something else and move on. Obviously you either are unhappy with your purchase, have buyers remorse, or trolling. Annnnd you just joined this morning to post this so I would expect trolling.
I just can't believe someone would pay $1,600 for a display and because the camera isn't fantastic the whole display is a "huge" waste of money.
Granted I'm not thrilled with the camera either but I didn't buy the display for the camera. I knew what I was buying and am happy for the most part. If I hated it like you it would be gone by now! These are hard to find and there are plenty of folks wanting them. You may even be able to make some extra $$.
For the record back in 2004 I paid $1,299 for a 20" Apple Cinema Display with no camera and no speakers. It was also a bit overpriced but people who buy Apple products know that going in.
