I don't know whether this thing is innovative or not -- I guess the near
future will show this clearer. But sometimes, "innovation" is not
necessarily a technical breakthrough. Like the GUI popularized by the early
Macs: there was nothing technically innovative in it, it was "just" the
specific way things were organized and working together. There was nothing
technically new in the first mouse, yet it was an innovation -- everybody
and his sister is using one today.
