My Apple Nanotubes are Here: A Review w/ Pics
The thickness of the silicone is little less than a millimeter, so the Nanotube adds very little to the size of the iPod. Also, the silicone covering the clickwheel is thinner, permitting the clickwheel to be sensitive to the touch. The only cutouts in the silicone are at the screen and the dock connector and headphones ports (slit at bottom nearly the width and thickness of the iPod). The hold switch is completely covered with silicone, though the silicone covering the switch protrudes out a bit, allowing you to move the switch with your nail.
The silicone is translucent enough that I can see my engraving on the backplate. The silicone is actually imprinted with menu, the rewind, fast-forward, and pause symbols on the front face, and the Apple logo and iPod name on the back face. Also, I should add that the nanotube edges on the front face of the iPod are squared, whereas the edges on the bottom face are rounded.
As for the colors, the blue tube is actually not that brighton my white iPod, it looks just like the image on the Apple website. The pink and green tubes are very bright and neon, though they probably would look more toned down on the iPod (I havent tried them out yet).
The Nanotubes fit very snuggly on the iPodI had trouble getting the nanotube on my iPod. Ive kept the factory sticker on the screen, as well as a PalmPilot screen protector I cut out for the backplate. Im trying to make up my mind whether to replace the factory sticker with the Pelican Screen Guard for the Sony PSP or one of the screen protectors made for the iPod nanolet me know your suggestions.
I definitely recommend the Nanotubesgreat fit which permits easy, sensitive use of the clickwheel. Of course, the only downside is that the screen is not protected, so a screen protector is a must.
