First impressions are good. It makes my 24" LED Cinema Display look pitiful (both size and resolution-wise). I noticed a speck of dust under the glass, which took literally 2 seconds to fix: suction cup the glass and blow the dust out with my compressed air. Didn't even need to turn the system off to do that either. Just did it on my desk. Easy. Does my iMac have any yellow tinge? Wait for it! NO!!!!! Hah, no I'm kidding. Yes it does. Very slight yellowing toward the bottom third of the screen. This falls in line with EVERY SINGLE LCD I'VE EVER OWNED!!! Seriously, people! Get over it! You're never going to find a screen without some form of color bleed. It's NOT possible with the current tech. Yes, I'm sure some screens are "better" than others, but really, panel variance is all that is. It's so funny watching people go mad about the tinge, when both my 24" LED Cinema Displays have a tinge, and they're from 2008! And guess what? My MacBook Pros have a tinge, too! And guess what? My old Dell 2407WFP had a tinge, too! And guess what? My Samsung 46" LCD TV has a tinge, too! Anyway, SO FAR so good. Only had it on about half an hour - did my upgrade to 8GB by adding 2x 2GB Crucial sticks, and she fired right up. It hurt my fingers to get the RAM in. Anyway, now I have to use this for a bit and then do the SSD upgrade. Enjoy your iMacs, people! First impressions are just amazing with this puppy.
