"Out of focus" was my first thought when looking at the brushed-metal looking button panels. They aren't hard to make, there are some really good tutorials online for making them in PS. A little blur is good, but I'd start off with a little more "crisp" brushed metal texture. Also the blur running across the different textures flattens it out some where the eye is expecting to see something more 3D. Just an amateur's opinion, offered up with constructive intent.
