I've just had the chance in the past few hours to really play with the device. I find myself smiling each time a new SMS bubble pops up. I love it. I also like seeing my friends' faces on my phone. I love being able to navigate my content and messages via my friends. Loved how easy it was to set up my email, Facebook, and Twitter. Packaging rocks ... and is recyclable. What is subtle in this device, in my opinion, is how intuitive the UI is. The UI looks and feels similar to others I have seen, but I was able to pick up this phone and use it without reading the instructions.
My colleague Charles Golvin will provide a more in-depth analysis of the device itself.
From a social networking/media perspective, the KIN is a good start, but I hope to see more with upcoming releases, especially around helping people build their social graph. I don't put this burden on Microsoft alone, but on the industry and all handset manufacturers. The content we create needs more meta data or labels. We need logic to mesh this content together and navigate through it. It's great that I can navigate to my friends' status and messages through my contacts (and KIN's UI is a lot of fun). I also want to navigate through my photos and location. Location should be table stakes for photo/status/review (restaurant/bar) content and the logic shouldn't flow in just one direction. Based on my location (simple location or map), I want to see who is nearby or what restaurants my friends liked. Navigating through my friends, I want to see what restaurants they liked. I want to group photos by location. I want to group photos by friends. These are just a few examples. With every product and service developed, one can't have everything. There are cost, time and design trade-offs. I completely understand that the KIN and DROID and others couldn't get everything done in v1.0. I look forward to the next version.
