As some of you may know I bought two iPod minis as I was unsure of which colour I preferred. I now have a pink and a blue one, I prefer the blue one but the feel of the click wheel is significantly better on the pink one. Particularly the centre button which goes along way down and clunks on the blue one whereas it is a nice short quiet click on the pink one. The wheel actually also moves a little inside the metal of the blue mini but not the pink one. I was wondering if the buttons deteriorate over time? and maybe the pink one will end up like the blue anyway? I can't decide which to keep right now I am very surprised however at the discrepancy in quality between two brand new minis and I much prefer the old 3G iPod touch sensitive centre button.
