Microsoft Surface Ring - Concept

While everyone is excited about the future smart watches that will be launched soon enough, I have a different idea regarding the next thing in wearable devices - why not a notification ring? As a Microsoft fan, I used inspiration from their key products to create a simple, yet detailed concept. The full presentation of the concept can be seen in the attached file or at http://dribbble.com/shots/1213434-Ring-Shot/attachments/162241

For designing the ring I used Illustrator and Photoshop, the Segoe UIfont-family and the following freebies:

The rest are product images from their official sites and the image with the African-American model was bought from Dreamstime.

For the icons, most of them I created from scratch, but for some I got inspired from http://modernuiicons.com/

As a reminder, this is just an idea of mine turned into concept, I respect all the companies illustrated in the infographic and it doesn't represent any official plans from their behalf and no harm is intended. To put it simple, I love design challenges. Also I collected some valuable feedback and I am working on the next iteration, for now calling it - MS Surface Ring Pro. Any other feedback is also must appreciated. Thank you and enjoy!
