Well I have now had my iMac for 4 days where I have been using it pretty extensively and I honestly say, I couldn't be happier! I was extremely worried after reading about some problems that people had had with theirs, but then I remembered, people more often than not, come to to forums to complain / talk about problems then they do talk about how happy they actually are. I'm sure for every 1000 iMacs, only 1 has a problem. Just to add, my iMac was assembled in Ireland. After unboxing it, before its first boot, I checked for any cosmetic damage i.e. scratches and scuffs and did not find any at all. After turning it on and setting it all up, I very quickly checked for dead pixels and none have been found. I have absolutely no image retention, no yellow screen and no light bleed. I am also absolutely amazed by the quality of the speakers! Unlike others have said, they do not in the slightest sound tinny. I have had many people come round to see it and they all think the speakers are of the most amazing quality. I also cannot get over how loud they are. I don't turn them anywhere near the maximum volume and they are still extremely loud and clear. As for the screen, WOW! It is crystal clear! It goes above and beyond all of my expectations! The colours are amazing! Again, I don't even have my screen brightness above 50%, yet it's still amazing. I also cannot believe how bright and clear it is when turned up to 100%. I was worried about how big the 27" screen was going to be, but after getting used to it, it's just perfect! The 21.5" just seems tiny now. The 27" inch is perfect for me doing photo/video editing, gaming and even just web browsing and emails etc. The speed and performance of this iMac also blow anything else (apart from the Mac Pro) out of the water! I have the 27" 3.4Ghz i7, 1TB fusion drive, 24GB RAM and 680MX 2GB. I have thrown everything I can at it and there has been no slow down or lag at all. It completes everything instantly. Finally, as for the design, I truly believe that it is a work of art. Many have said that from the front it looks no different to the 2011 model, but combined with the full lamination technique used for the screen, I completely disagree. When I walk passed it and see the 5mm edge, it's fantastic! Even the bulge (wrong word really as it is hardly very big) is very nice and rounded. Overall, I would just like to say well done and thank you to Apple for providing me with this amazing machine and an amazing operating system. Coming from using Windows all my life, this truly has showed me the full potential of a computer. Never will I ever go back to running Windows. And to people thinking about buying their own late 2012 iMac, go ahead! You really won't regret it!
