I haven't read all the threads with complaints, but I just wanted to post to say that I've had my new iMac for 36 hours and I love it. I've been waiting to upgrade for over a year, and I'm coming from an April 2008 iMac 24" 2.8GHz Core2Duo/6GB/500GB/ATI2600HD I now have 27"/i7 3.4GHz/8GB(+16 on order)/3TBfusion/680GTX it arrived a week before the estimated delivery date! it really does look thin. I know it doesn't "matter" as such, but it does look a lot more elegant on my desk. The build quality appears superb Aperture runs loads faster I don't know what they've done to the screen, but the amount of reflection is massively reduced (see pic attached) The monitor is decently calibrated out of the box; the ColorMunki only made minor adjustments (and you can actually manually turn down the brightness to a sensible level (out-of-box mid brightness is 110cd/m2), unlike previous models). My display appears uniform whatever colour is on screen, I haven't seen any dead pixels and there's no backlight bleed or intrusion at the brightness I'm using (120cd/m2) The SD card reader is easier to reach than I thought it would be, being around the back Aperture really shouldn't stop you using it for anything else when you're consolidating a previously-referenced library from external disc to internal (42000 pics - took half a day over USB3!) X-Plane 10 has become loads more fun Hope that's encouraging for anyone unsure about whether the 2012 model is good enough!
