I have to admit when the new iMac was released I was very surprised by the design. With iPads and iPhones losing their bezels and chins, I was certain the new iMac would have followed the same design. When first announced, I really disliked the look.
After watching a lot of reviews on the new iMac, and seeing it in comparison to the Intel iMac, my opinion has changed quite a bit. The lighter bezel does seem to blend in well with most backgrounds and looks very nice when compared to the black bezels on the previous iMac (though the Intel iMacs did have quite large bezels which may be partly the reason).
The missing logo on the chin, though not a big deal, would have helped break up the chin a little and possibly prevent it from sticking out so much.
Overall, the new iMac looks like a great machine and I actually really like the design choices they made (though I did not at first).
