I'm debating with myself right now whether to pick up the 24" LED ACD (before its sold out at all the apple stores as well as it being $200 cheaper and noticed student discount is $100 off additionally) or to wait for the 27" LED ACD. Things that worries me about the 27" LED ACD: 1) Might have yellowing issues like the current 27" iMacs. 2) Other problems with the 27" LED ACD like the first revs such as horizontal line issues or display lowered brightness buzzing issue (like the current 27" iMacs). 3) Far higher % of receiving dead/stuck pixels as it has a much higher pixel count. 4) Heat issues. 5) Bad backlight bleeding issues (usually bigger displays have this problem). 6) Resolution is too high to read text from a good distance. I hear some people saying that the 24" LED ACD is the perfect size/resolution and that the 27" iMac's resolution is "TOO SMALL." I've owned the 24" LED ACD since the first time it was released but sold it about 6 months ago and I regret it ever since. The 24" LED ACD that I had was perfect with no issues such as backlight bleeding or yellowing at all and so far I've been through a few displays and have always been dissatisfied with its quality. I suppose nothing beats the H-IPS panel + LED backlighting combo. I'm so eager to pick up the 24" tomorrow but everytime I look at the 27" iMac's display it makes me want to wait for the 27" LED ACD.
