I've just recieved an iPod Photo 60GB but I'd just like to hear people's opinion of something I've noticed about the casing of the iPod. Basically, on all but the left side of the iPod, when I run my finger from the metal and onto the white front, there is no noticeable different in 'feel'... the two surfaces meet nicely. However, on the left side, my thumb 'catches' when running my thumb over it. Basically, the white front sits out slightly from the metal on the left side. If it was just a generic MP3 player, not a £300+ iPod, I probably wouldn't be worried, but is this something all iPods exhibit, or should I ask for a replacement?
