These look great but this quote from John Gruber says it best:
The designs in these concept videos are free from real-world constraints — technical, logical, fiscal. Dealing with constraints is what real design is all about. Institutional attention on the present day — on getting innovative industry-leading products out the door and creating consumer demand for them — requires relentless company-wide focus.
This will never see the light of day in this form once the reality of getting the interface right and making it fit into a pair of glasses that people will wear. Still it is good to dream.
