Let me start off this post by saying if you are reading this blog here on ZDNet then you are most likely NOT the target market for these new phones. Microsoft purchased Danger and then set out with a distinct project team designed to create a mobile phone experience for the people in their teens to late 20s. They created and ran a rather incredible program with real young people and I have to say I am still quite amazed that all of these people were able to keep the project so quiet. I had the pleasure of hearing all about "Pink" (now known as Kin) at Mobius last Fall and think that my teenage daughters would love to have these devices. When Microsoft rolled out Pocket PC several years ago they took the PC and shrunk it down to a handheld form factor and thankfully they started from scratch here and created an operating system that looks nothing like a desktop PC. It is modeled more after a magazine and now that you have seen Windows Phone 7 you can understand that "Pink" phones are a slightly different slimmed down version that may serve as perfect first devices before people move up to a WP7 device.
Rather, take a look at Kin and then compare BREW, Bada, and other feature phone operating systems. Kin phones are much more capable with Zune integration, advanced social networking capabilities, an intuitive and customizable user interface, and plans that allow young people to actually use their smartphones.
