Well, I decided to hop into our local Apple Store and pick up one of the 21" models 2.9 i5 8GB. This Mac is on our breakfast bar which adjoins our great room. The sides and back are prominently in view. I carefully viewed it next to our 2011 iMac and can say - from this owners eye & perspective - that it is STUNNING. A well executed and aesthetic profile. Some of the photos had me wondering but we think it is great. 5400 rpm drive / quiet, even while indexing. Will be ordering some sort of SSD external shortly for boot and apps. The screen does "pop" more - colors are vibrant - even illumination - and the reflections are almost all gone - thumbs up. Very light weight. All in all - happy camper after setup and limited use.
