You are correct, it does seems like a minutiae indeed. I even took a video of it, just because the part peeled away (like you said). The problem is, once I saw that, I couldn't 'unsee' it. I started pressing the area of the backplate around the camera, and saw that it flexed quite a bit.
I don't change phones often, and I was looking forward to this one. But after I saw this, I decided that I'm going to check out the a Motorola with ICS...... if that doesn't happen by January end, I might jump ship to Windows Phone 7 with the Lumia.
