A report from Baptiste.
I just purchased an 8GB iPod nano, silver model, in Canada. After unpacking it, I realized that the display is not straight and slightly rotated on the left. I went back to the shop to get it exchanged, unpacked it right on the place, and same thing
When browsing the web, it quickly found 2 websites reporting about this issue:

the defect is barely visible, but this is the first time that the iPod suffer such a quality control assembly defect. Apple should strengthen its quality control levels directly from its contractors.
