So who else noticed the touch cover color options?
Black, White, Red, Cyan, and Magenta. All but one of those has a matching model Lumia 800/900 (and maybe the red is just teasing the Verizon unicorn). I would find it hard to believe this wasn't intentional. Part of the motivation for building their own hardware to begin with is due to image. Apple likes to entice people with the "full set" of MacBook/iPhone/iPad that are all designed to match each other, something Microsoft wouldn't be able to do with a generic looking tablet from [insert oem]. By giving a visual nod to their flagship phone, they can look a lot better when they push the integration between platforms.
